In the context of reduced cultivated land and increasingly scarce water resources, increasing rice production has become an urgent problem in order to meet the needs of world's growing population. On the basis of previous work, this paper combines the entropy weight method with the fuzzy comprehensive evaluation method to expand the method of comprehensive evaluation of rice quality. The main purpose is to establish an entropy weight fuzzy comprehensive evaluation model and apply it to comprehensive evaluation of rice quality of japonica rice variety in 12 different producing areas. At the same time, identity the marker genotypes of parental yield traits, and found 31 marker genotypes are significantly correlated with the yield of parental yield traits. The two marker genotypes are related to the six traits of the parent; two marker genotypes are related to the 5 traits of parental at the same time; there are four marker genotypes associated with the four traits of the male parent; There are five marker genotypes associated with maternal features; there are three marker genotypes associated with the parental and maternal genetic traits; There are 15 marker genotypes associated with parental traits of individual traits. The marker genotype of the RM23~150/160 was positive for 4 genotype effects. The number of per panicle, daily yield per plant, ear length and number of secondary branches increased by 12.1%, 11.3%, 10.4% and 14.9%, respectively. The results showed that the whiteness, different cultivar rate, defect rate and amylose content may be the main indicators affecting differences in quality of various varieties’ rice.

However, the problem of pesticide residues is becoming more and more serious due to the extensive use of pesticides, potential teratogenicity and carcinogenicity pose a serious threat to consumers' health. In order to control the pollution of organophosphorus pesticide residues, besides strengthening the management of pesticide use, the key is to develop simple, fast and sensitive detection technology. Because soybean contains more oil and fat than cereals, it brings many difficulties to the analysis of pesticides. So far, there is no mature method in China. Based on the above background, the aim of this paper is to determine organophosphorus pesticides in soybean by gas chromatography. In this paper, the extractant and sample purifier of organic phosphorus in soybean were discussed, and the organophosphorus pesticides in soybean were extracted with acetone-dichloromethane mixed solvent, and Flori silica was used as purifying agent. The residues of four organophosphorus pesticides in soybean, dimethoate, methyl parathion and parathion, were determined by gas chromatography with flame photometric detector. Simple operation, high recovery and minimum detection concentration are as follows: dropping fear 0.03 mg/kg; dimethoate 0.04 mg/kg; methyl parathion 0.04 mg/kg; parathion 0.05 mg/kg. bicyclo germare (8.4%), trans-nerolidol (19.5%) and 9-oxaaryl alcohol (7.7%).

The treatment and development and utilization of crop straw have become the focus of attention from all walks of life. In order to improve the utilization rate of crop stalks, save energy and protect the environment, this article conducted an in-depth study on the two-phase high-temperature anaerobic digestion test of crop stalks. First, the response surface method is used to control the organic loading ratio and the inoculation ratio respectively, and analyze the daily methane production and daily cumulative production. The test results showed that the A5 group on the 5th day (the organic loading ratio was 20gVS/L) had the highest single-day and cumulative methane production, which were 6.15mL/gVS and 19.57mL/gVS, respectively. When the inoculation ratio was 0.4 on the 25th day, the B1 group had the highest methane production, which was 2.88 mL/gVS. Then, the rice straw was treated by ammoniating treatment and multi-strain cooperative treatment to analyze the differences in pH value, ammonia nitrogen content and lignocellulose degradation rate. The test data showed that the pH values of the two groups were between 7 and 8. The ammonia nitrogen content of the ammoniated treatment reached 4485.1mg/L, and the degradation rates of lignocellulose on the 35th day of the ammoniated treatment and the multi-strain co-treatment were 24.14% and 35.33%, respectively. This shows that the effect of multi-strains synergistic treatment is better than ammoniated treatment, with lower ammonia nitrogen content and higher lignocellulose degradation rate. Finally, under the same experimental conditions, two-phase high-temperature anaerobic digestion experiments were carried out using rice straw and corn straw, respectively, to analyze the differences in pH, ammonia nitrogen content and lignocellulose degradation rate. The pH values of the rice straw and corn straw reactors were 7.56 and 8.21, the ammonia nitrogen content was 984.2 and 1128.6 mg/L, respectively, and the lignocellulose degradation rate was 34.54% and 25.38%, respectively. This shows that under the same reaction conditions, rice straw is better than corn straw, has lower ammonia nitrogen content and higher lignocellulose degradation rate, and its gas production and utilization are higher.","PeriodicalId":396836,"journal":{"name":"Academic Journal of Agricultural Sciences","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127677566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In crop growing season, the dynamic changes of crop growth can be determined by different time series images. Therefore, remote sensing technology has the advantages of fast, accurate and strong current situation, it has increasingly become an important means of monitoring the dynamic changes of crop growth in a large area. Monitoring crop growth by remote sensing is of great significance for dynamic perception of food security. The purpose of this paper is to analyze the monitoring data of soybean growth under ecosystem by remote sensing technology. On the soybean scale, based on the difference of reflectance caused by the change of water structure, a method for screening and monitoring the sensitive characteristics of soybean growth was proposed. By measuring the spectral data of soybean growth potential samples, based on the characteristics of surface albedo, vegetation index and detail, and combined with correlation analysis and SVM and GASVM, the growth monitoring model on soybean scale was established. The characteristics of sensitivity to soybean growth and significant difference were screened out, it includes three characteristic bands of 340-380, 480-580 and 750-1000 nm, and three vegetation indices of MSR, NDVI and SIPI, WF01 and WF02 are two wavelet features.

The growth cycle of corn is longer and the process is more complicated. In addition to being affected by internal physiological mechanisms, the growth of maize has a great influence on its growth environment, especially the light environment. During the growth process, the interaction between corn and light environment is constantly underway. Corn planting time is also an important factor affecting corn yield. The difference in sowing date directly affects the growth and development stages of corn. The purpose of this paper is to study the growth pattern of corn based on a statistical model of yield. In terms of methods, it is proposed to use the inverse ray tracing algorithm to calculate the light energy reflected and absorbed by the corn, and establish a model to analyze the sensitivity of the area, mainly in terms of leaf area index, temperature, and moisture to analyze corn yield. Establish a corn growth model, and construct it from four aspects: yield, photosynthesis, temperature, and moisture. Finally, comprehensive supplements were made, and planting conditions continued to be optimized at planting density. In terms of experiments, the meteorological data and soil parameters of the plantation site were investigated. Finally, the experiment was divided into four groups, one was for home planting; the other was for planting at different intervals, the other was normal; the three were for drip irrigation, and the other was normal Four groups were planted using the improved strategies proposed in this paper. It is concluded that under drip irrigation conditions, the grain filling rate can be significantly increased, which will lead to an increase in 100-grain weight during maturity. With the increase of the population density, the competition among individuals within the group for light, temperature, water, and fertilizer is intensified. For better individual development, the individual plant height and ear height have been continuously increased in order to obtain more light energy","PeriodicalId":396836,"journal":{"name":"Academic Journal of Agricultural Sciences","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131144929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
