根据我区试验,麦茬覆膜花生比露地栽培平均增产约38.3%,667平方米产量在300公斤左右,高产田在400公斤以上,经济效益很好。其主要栽培技术要点如下。 1.土壤选择。要选择土层深厚、肥沃、有水浇条件、灌排方便的沙壤地,以充分发挥覆膜栽培的增产潜力。旱薄低产田不宜覆膜栽培。 2.合理施肥,将氮、磷、钾、微肥等配合使用。因为花生覆膜后追肥困难,故采取播种前1次施足底肥的方法。根据花生吸肥特点,对667平方米产量400公斤以上的高产田,一般667平方米施优质有机肥3000公斤、碳酸氢铵30~40公斤、硫酸钾10~15公斤,并配合施入一定数量的硼、钼、锌等微量元素肥料。
According to my district test, the stubble mulching of wheat stubble increased production by about 38.3% compared with the open field cultivation, the yield of 667 square meters was about 300 kg, and the high-yielding field was over 400 kg with good economic benefits. The main cultivation techniques are as follows. 1. Soil selection. To choose a deep soil, fertile, water conditions, irrigation and drainage convenience of the soil to give full play to the yield potential of plastic film cultivation. Dry and low yield fields should not be covered cultivation. 2. Rational fertilization, the nitrogen, phosphorus, potassium, micronutrients, etc. used in conjunction. Because of peanut top dressing difficult, it is necessary to apply before sowing the method of footing fertilizer. According to characteristics of peanut absorption, on 667 square meters of yield of more than 400 kilograms of high yield fields, generally 667 square meters of high quality organic fertilizer 3000 kg, ammonium bicarbonate 30 to 40 kg, potassium sulfate 10 to 15 kg, and with a certain amount Of boron, molybdenum, zinc and other trace elements fertilizer.
