Abstract
The purpose of this study is to investigate the fertilizer and fertilizer use conventional fertilization on wheat production, provide technical basis for the rational use of chemical fertilizers. Using field randomized block experiment, through the formulation N187.5 kg, P90.0 kg, K60.0 kg, N187.59 kg, P90.0 kg, N187.5 kg, K60.0 kg, P90.0 kg, K60.0 N157.5 kg kg and conventional P88.5 kg, K88.5 kg, N157.5 kg, P88.5 kg, N157.5 kg, K88.5 kg, P88.5 kg, K88.5 kg fertilizer rate comparison, the utilization rate of nitrogen, phosphorus and potassium fertilizer materials and the impact on production. Results show that the plastic film mulching cultivation under a g a, fertilizer than average wheat yield of 537.75 kg/hm2, increase 7.31%. Fertilizer use efficiency increased by 12.51%, 2.4% (2.4% nitrogen, phosphate, potash) conclusion: in longdong HanYuan or poor fertility zone production level, the formula ratio N12.5: P6: K4, using plastic film mulching cultivation, soil testing formula fertilization of wheat nitrogen fertilizer utilization rate was 37.4%, the utilization rate of 24.1% phosphate fertilizer, potash fertilizer utilization rate of 43.0%. Conventional fertilization of wheat nitrogen fertilizer utilization rate is 35.0%, utilization rate of 21.9% phosphate fertilizer, potash fertilizer utilization rate of 35.1%. Fertilizer compared with conventional fertilization, has significant stimulation effect, can significantly improve the utilization rate of fertilizer application should be promoted.
Highlights
Winter wheat is the main food crops in longdong region, perennial plant area of 267000 hm2, accounts for 50-55% of the area sown to grain production level is only 3000 kg/hm2 [1]
In response to the production of wheat fertilization is not standard, reduce fertilizer waste events continue to occur, longdong HanYuan jingchuan county agricultural extension center combining with soil fertility conditions and rules of wheat needs fee, according to the soil itself to protecting fertilizer, fertilizer ability, development and implementation of organic manure and chemical fertilizer, nitrogen fertilizer and under appropriate proportion, to establish a set of suitable for HanYuan of fertilizing the balance of soil science
In 2005 the ministry of agriculture issued by the measured soil fertilizer specification "" 3414" plan is recommended for the design
Summary
Winter wheat is the main food crops in longdong region, perennial plant area of 267000 hm, accounts for 50-55% of the area sown to grain production level is only 3000 kg/hm2 [1]. Due to soil nutrient unbalance, lead to wheat transformation of nutrients, affect the wheat yield and quality. This cause pollution to the ecological environment [4], increased crop production costs, reduce crop yield and quality, reduce the agricultural income. This article in the 2012-2015, on the basis of "3414" experiment, through the contrast test of wheat field nitrogen, phosphate and potash, ascertained the HanYuan arid area measured soil fertilizer and wheat under conventional fertilization of nitrogen, phosphate and potash use present situation and the use efficiency, to longdong loess or poor
