对杂交棉高产栽培优化组合进行了7个点的反馈示范。结果表明,采用适当增加种植密度,合理经济施用氮、磷、钾肥,合理化调等措施,实现了节本增产增效的目的,验证了五因素五水平试验结果的准确性和该研究成果在大面积应用的可行性,为推广杂交棉高产栽培优化组合配套技术提供了实践参考。
Seven-point feedback demonstration was carried out on the optimal combination of high-yielding cultivation of hybrid cotton. The results showed that the purpose of increasing production and increasing efficiency was achieved by increasing planting density, rational economic application of nitrogen, phosphorus and potash fertilizer, reasonable adjustment and other measures. The accuracy of the five-factor and five-level test results was verified and the results of the research were large The feasibility of application of the area provides practical reference for popularizing the high-yielding hybrid cultivation of hybrid cotton.
