本文对棉麦两熟晚春套棉花施纯氮量、灌溉定额对棉花籽棉产量的影响进行了研究。建立了晚春套棉籽棉产量与施纯氮量、灌溉定额间的函数模型,并对施纯氮量与灌溉对产量影响的交互作用做了进一步分析。通过数学模拟筛选出每亩210kg以上籽棉产量的最佳农艺措施方案。
In this paper, cotton and wheat two ripening in late spring cotton sets of pure nitrogen, irrigation quota on cotton seed cotton yield were studied. The function model of yield and nitrogen application rate and irrigation quota of cotton seed cotton in late spring was established. The interaction between nitrogen application rate and irrigation yield was further analyzed. The optimal agronomic measures for seed cotton yield above 210kg per acre were screened through mathematical simulation.
