1983年我局在双田乡门坊村,用“粤选58”作春播和夏播试种,单位面积产量486.7斤,比种植多年的早熟当家种“六月爆”亩产高200余斤。 现将试种中的栽培方法小结如下: 一、整地与底肥 选择沙质壤土稻田,翻耕前亩施红花鲜草2000斤(也有用猪牛栏20—30担的)、石灰50斤。底肥中还加施速效化肥氮、磷、钾,计纯磷5斤、纯钾4斤、纯氮2斤,以满足幼苗生长和花芽分化对养料的需求。施肥后,干翻干耙作畦,畦宽4—4.5尺、沟宽1尺。
In 1983, our bureau carried out spring sowing and summer sowing trials in the village of Shuangtian Township in Fangcun, Shuangtian Township. The yield per unit area was 486.7 kg, more than 200 kilograms more than that of the “June burst” acreage planted with many years of planting. Now the cultivation methods in the trial are summarized as follows: First, the choice of soil preparation and the end of the sandy loam paddy soil, before tillage acres of fresh red grasses 2000 kg (also useful for pigs 20-30 Tam), lime 50 pounds. The base fertilizer also added quick-acting fertilizer nitrogen, phosphorus and potassium, accounting for 5 pounds of pure phosphorus, 4 kg of pure potassium, 2 kg of pure nitrogen to meet the seedling growth and flower bud differentiation on nutrient needs. After fertilizing, dry dry rake for 畦, 畦 wide 4-4.5 feet, 1-foot width.
