摘要
2018- 2019年，在达卡Sher-e-Bangla农业大学土壤科学系的一个网屋进行了盆栽试验，以确定肥料在Madhupur地块工业污染农用地土壤中对Boro和T. Aman水稻生长和产量的影响。试验包括2个因子，即污染土壤，S1:未污染土壤，S2:污染土壤-1,S3:污染土壤-2,S4:污染土壤-3,4个施肥处理，T0:对照，T1: N150P30K60S20Zn3.0 (100%RDCF)， T2: N105P21K42S14Zn2.1 (70%RDCF)， T3: N75P15K30S10Zn1.5(50%RDCF)。试验采用随机完全区组设计(RCBD)， 3个重复。土壤中，土壤S2(污染土壤-1)的米粒产量最高，为90.83 g pot-1，土壤S1(未污染土壤)的米粒产量最低，为41.66 g pot-1。T3(50% RDCF)肥处理的水稻株高(84.12 cm)、有效分蘖(42.5 hill-1)、秸秆(112.58g pot -1)和籽粒产量(80.03g pot -1)最高。在2种工业污染土壤(S2和S4)中，水稻的籽粒和秸秆产量均较高。籽粒产量最高的是S2T3(污染土壤1和50% RDCF)，与S4T2和S4T3具有统计学上的相似性，最低的是S1T0处理组合。土壤S2(污染土壤-1)和土壤S4(污染土壤-3)籽粒产量最高(38.75gpot−1)。T. Aman水稻产量以T2处理最高，为36.68 g，与T1处理相近。同样，在S2T1(污染土壤1和100% RDCF)处理下，T. Aman籽粒产量最高，与S2T2、S4T1和S4T2具有统计学上的相似性，S1T0处理组合产量最低。T. Aman秸秆产量最高的是S3T1处理，最低的是S1T0处理。孟加拉国阿格龙。[j] .中国生物医学工程学报，2016,26(1):112-121
Effect of Fertilizer on the Growth and Yield of Boro and T. Aman Rice in the Soils of Industrially Polluted Agricultural Land Areas of Madhupur
A pot experiment was conducted during 2018-19 in a net house at the Department of Soil Science, Sher-e-Bangla Agricultural University, Dhaka, to determine fertilizer's effect on the growth and yield of Boro and T. Aman rice in the soils of industrially polluted agricultural land areas of Madhupur Tract. The study consisted of two factors, i.e., polluted soil viz., S1: Non-polluted soil, S2: polluted soil-1, S3: polluted soil-2, S4: polluted soil-3, and four fertilizer treatments viz., T0: Control, T1: N150P30K60S20Zn3.0 (100%RDCF), T2: N105P21K42S14Zn2.1 (70%RDCF) T3: N75P15K30S10Zn1.5(50%RDCF) The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Among the soils, the highest Boro rice grain yield of 90.83 g pot-1 was found in S2 (polluted soil-1) soil, and the lowest 41.66 g pot-1 in soil S1 (Non-polluted soil). The treatment T3(50% RDCF) fertilizer treatment gave the highest plant height (84.12 cm), effective tillers (42.5 hill–1), straw (112.58g pot –1) and grain yield (80.03g pot−1) of Boro rice. The higher grain and straw yields of Boro rice were obtained from two industrially polluted soils (S2 and S4). The maximum grain yield (112.3g pot–1) of Boro was found in S2T3 (Contaminated soil 1 and 50% RDCF) , which was statistically similar to S4T2 and S4T3 and lowest in the S1T0 treatment combination. The maximum T. Aman grain yield (38.75gpot−1) was obtained in soil S2 (polluted soil-1), which at par to S4 (polluted soil-3). The maximum T. Aman rice grain yield (36.68 g pot−1) was found in the T2 treatment, which was closely by T1 treatment. Similarly, the maximum T. Aman grain yield was obtained in S2T1 (Contaminated soil 1 and 100% RDCF) which was statistically similar to S2T2, S4T1, and S4T2 and lowest in the S1T0 treatment combination. The highest T. Aman straw yield was found in the S3T1 and lowest in the S1T0 treatment combination.
