要获得西瓜丰产,达到质优、耐贮运,肥水管理是关键。总结我校西瓜栽培试验的施肥经验,可归纳为“一重、二促、三控、四保、五催、六防”。具体作法如下: 一重:即重施基肥。每亩用人畜粪50担,垃圾肥100担,饼肥150公斤,过钙37.5公斤,混匀后发酵,然后加草木灰37.5公斤(每亩250株瓜,每株需用人畜粪10公斤,垃圾肥20公斤,饼肥0.6公斤,过钙0.15公斤草木灰0.15公斤)。二促:即促幼苗快速生长。在第2朵雄花出现前以施氮肥为主,少量多次。结合气候情况,在瓜苗周围开沟。宽、深10—15厘米,阴雨天干施覆土,晴天傍晚液施,每5—8天1次,每亩用铵态氮肥10—12.5公斤。三控:即控制用量。防疯长跳藤和花而不实。于5
To get high-yield watermelon, to achieve high quality, storage and transportation, fertilizer and water management is the key. Summarize my school watermelon cultivation experiment fertilization experience, can be summarized as “a heavy, two promote, three control, four guarantees, five reminders, six defenses.” Specific practices are as follows: One heavy: that is, heavy base fertilizer. 50 mu for human and animal manure per mu, 100 for garbage manure, 150 kilograms of cake fertilizer, 37.5 kilograms of calcium, mix and ferment, then add 37.5 kilograms of plant ash (250 cucumbers per mu, 10 kilograms of manure and manure for each plant, 20 kilograms, cake 0.6 kilograms, 0.15 kilograms of calcium ash 0.15 kilograms). Promote two: Promote the rapid growth of seedlings. In the first two male flowers before the emergence of nitrogen fertilizer, a small number of times. Combined with the climate, ditch around the melon seedlings. Wide and deep 10-15 cm, overcast soil cover dry, sunny evening liquid facilities, every 5-8 days 1, with ammonium nitrogen fertilizer per acre 10-12.5 kg. Three control: that control the amount. Anti-crazy long jump vine and flowers but not real. At 5
