一、品种。选适应性强,抗病性好,稳产、丰产及纯度高的新良种。 二、整地施肥。前茬作物收获后,要抓紧时机浅耕灭茬和施足底肥(有机肥),然后深耕20厘米左右,争取早歇、早晒,以利土壤风化和有机物的分解,减少病虫害。采取垄作栽培,垄高为10～15厘米,施腐熟的有机肥,亩施基肥500公斤左右,为防治地下害虫,浅耕前亩喷撒2.5敌百虫粉剂或5％西维因粉剂2～2.5公斤进行土壤消毒。
First, the variety. Select adaptive, good disease resistance, stable yield, high yield and high purity new varieties. Second, soil preparation and fertilization. After harvesting the stubble crops, we must pay close attention to the timing of planting tillable stubble and application of base fertilizer (organic fertilizer), and then cultivate about 20 cm for early break and early drying to facilitate soil weathering and decomposition of organic matter to reduce pests and diseases. To ridge cultivation, the ridge height of 10 to 15 cm, applied maturity of organic fertilizer, 500 kg of basic fertilizer per acre for the control of underground pests, mu shallow spray 2.5 trichlorfon powder or 5% 2.5 kg for soil disinfection.
