Abstract:

In order to investigate the soil nutrients of high-yielding cotton in southern Xinjiang during the “Eleventh Five-year Plan”, a typical high-yield cotton in Bavaria for the study, fixed sampling in the seed cotton yield in 6750-7500 kg/hm2 of the cotton fields with two consecutive years. The results showed that, 48.33% of the sample total nitrogen content was low level; 63.33% of the sample alkali-hydro nitrogen content was medium level; 46.67% of the sample effective phosphorus was medium level; 61.67% of the sample of the effective potassium content was low level; 100% of the sample commutativity calcium, exchangeable magnesium, effective sulfur belong to high level; 81.48% of the sample of the effective boron content was medium level; 88.88% of the sample effective copper content was medium level; 77.78% of the sample effective iron content belonged to low level; 92.59% of the sample effective zinc content belonged to low level. In “Twelve Five-year Plan”, keep cotton plateau, production, we should pay attention to the use of potash fertilizer, and at the same time, to ensure the adequate use of organic fertilizer, reasonable fertilizer nitrogen phosphate fertilizer, trace element must take seriously to zinc fertilizer, iron fertilizer application, the boron fertilizer, copper fertilizer according to cotton growing moderate fertilizer.
