米薯间作是在不降低玉米产量的前提下,马铃薯偏得的种植方式,二者垄数之比为6:2。 1.品种选择玉米选择矮秆、耐密、喜肥水、抗倒伏的品种,如四密21和25、登海1号等。马铃薯选择脱毒、早熟、高产、抗病的新品种如绿芽早(55—60天成熟)。 2.整地施肥选择南北垄种植(因其通风透光条件好),翻地前深蹚一次。把发酵好的农家肥每10米1筐,同二铵10公斤、硫酸锌10公斤、尿素10公斤和微生物活绿宝3袋拌在一起,施入马铃薯垄底,然后起垄压实。在玉米垄同时施入二铵20公斤、硫酸钾15公斤、尿素15公斤、活绿宝1袋,
Intercropping rice is under the premise of not reducing the yield of maize, potato planting mode, the ratio between the two ridge 6: 2. 1. Selection of varieties Select corn dwarf, tolerance dense, like fertilizer, lodging varieties, such as four 21 and 25, Denghai 1 and so on. Potato selection detoxification, precocious, high yield, disease-resistant new varieties such as green shoots early (55-60 days mature). 2. Land Preparation Fertilizer selection North and South ridge planting (because of its good ventilation and light conditions), turn the ground before the trip. The fermentation of a good manure 1 baskets per 10 meters, with 10 kg of diammonium, 10 kg of zinc sulfate, 10 kg of urea and microbial live Lvbao 3 bags together, applied to the potato ridge, and then Ridge compaction. In the corn ridge at the same time into the diammonium 20 kg, potassium sulfate 15 kg, urea 15 kg, live Lvbao 1 bag,
