四、栽培技术措施 1.基本条件每生产100斤小麦约需吸收氮3斤,磷1斤,钾3斤;消耗水分6—7万斤。实践经验证明:亩产800—1000斤的高产田一般含有机质1％以上,全氮0.08％以上,水解氮30ppm、速效磷20ppm、有效钾50ppm以上;在这个基础上,彻底平整土地,深耕,增施有机肥料,一般要求亩施有机肥(含氮、磷各0.2％左右,钾0.5％左右,当年利用率30％左右)1—1.5万斤,再补充过磷酸钙和氮素化肥(按硫酸铵折算)各50—100斤。底墒充足、保水性好的土壤,全生育期须浇水5—6次,高岗砂地适当增加浇水次数;因此,要充分挖掘水源,
Fourth, cultivation techniques and measures 1. Basic conditions Each kilogram of wheat produced about 3 kg of nitrogen to be absorbed, 1 kg of phosphorus, potassium 3 kg; consumption of 6-7 kg of water. Practical experience shows that the high-yield field with 800-1000 kg per mu generally contains more than 1% of organic matter, more than 0.08% of total nitrogen, 30ppm of hydrolyzed nitrogen, 20ppm of available phosphorus and 50ppm of available potassium. On this basis, The application of organic fertilizer, the general requirements Mushi organic fertilizer (nitrogen, phosphorus, about 0.2%, about 0.5% potassium, when the utilization rate of about 30%) 1-1.5 kg, and then add superphosphate and nitrogen fertilizer Ammonium sulfate conversion) The 50-100 pounds. At the end of sufficient soil moisture, good water retention of soil, the whole growth period to be watered 5-6 times, Gao Gang sand appropriate increase the number of water; therefore, to fully tap the water,
