摘要:
为探索锌肥对水稻产量的影响,掌握在水稻生产中锌肥的适宜用量,为指导农民合理 使用锌肥提供科学依据,2017 年开展水稻锌肥试验研究,结果表明:拟合得到水稻产量与施用锌 肥一元二次方程为:y=-33.4x2+98.121x+598.424(R2=0.8173);施用适量锌肥能增加光合作用,一 定程度上提高水稻的株高、有效穗、每穗粒数、千粒重,进而提高水稻产量;在试验地土壤肥力水 平下,亩施纯N 22 kg、P2O5 3 kg、K2O 4 kg 配方肥的基础上,锌肥用量0~1.47kg/亩范围时水稻产 量随锌
Abstract:
In order to explore the effect of zinc fertilizer on rice yield, master the suitable amount of zinc fertilizer in rice production, and provide scientific basis for guiding farmers to use zinc fertilizer reasonably, the experimental study of rice zinc fertilizer was carried out in 2017. the results showed that the quadratic equation between rice yield and application of zinc fertilizer was as follows: y=-33.4x2 98.121x 598.424 (R2 ≤ 0.8173); The application of proper amount of zinc fertilizer could increase pho? tosynthesis, increase plant height, effective panicle, grain number per panicle and 1000-grain weight to a certain extent, and then increase rice yield. Under the soil fertility level of the experimental site, pure N-22 per mu was applied. On the basis of kg,P2O5 3kg, K2O 4kg formula fertilizer, the rice yield in? creased with the increase of zinc fertilizer in the range of zinc fertilizer 0~1.47kg/ per mu, the rice yield was the highest in 1.47kg/ mu, the rice yield decreased with the increase of zinc fertilizer in the range of zinc fertilizer 1.47~2.93kg/ mu, and the rice yield did not increase but decreased when the amount of zinc fertilizer was higher than that of 2.93kg/ mu.
