Optimization of Cotton Fertilization in Central -South of Hunan
摘要
Abstract
In order to explore and establish the index system of fertilizer application of direct seeding cotton after rape,field experiment with “3414”design was carried out in Central -southern Hunan,and the data were analyzed by regression. The results showed that at the target of 4000 kg/hm2 seed cotton yield,the best fertilize amount is N∶P2 O5 ∶K2 O =227∶68∶218,namely,urea 487 kg/hm2 ,super phosphate 567 kg/hm2 and muriate of potash 363 kg/hm2.关键词
