从研究旱塬土壤水份、作物根系的结果中,探索出一种有前途的少耕法钻耕。即用钻具(手动、机动)在立茬田地上打出直径10Cm(15,20),深100Cm (150—200)的孔,孔口近旁(2—3Cm)移栽点播瓜、菜或农作物。孔数即作物密度。孔内用刮起的表土、农家肥、化肥混匀填充,肥料用量与一般翻耕相同,经济作物偏高。钻孔、填孔时间,一年一熟地区秋收后至翌年栽播前均可。粪土能在雨后湿态下孔最好。钻耕可避免破坏土壤结构,保留作物残茬,覆盖表土,减少蒸发及水土流失。提高生物孔内土壤疏松、肥沃,降水蓄到深处,透气良好,为根系创造一个相对良好的生活环境,根易下扎,使作物生长旺盛,产量提高。
From studying the results of soil moisture and crop roots in the highland, we have found a promising way to reduce tillage. That is, with drill (manual, motor) in the stubble field shot diameter 10Cm (15,20), deep 100Cm (150-200) hole near the orifice transplant (2-3Cm) transplanting point melon, vegetables or crops. The hole number is crop density. Hole with the blowing of topsoil, farmyard manure, fertilizer mix, the amount of fertilizer and general tillage the same, high cash crops. Drilling, filling hole time, a year after harvest area to harvest the following year before planting can be. Dung soil in wet state after the rain best hole. Drilling can avoid damaging the soil structure, retaining crop residues, covering topsoil, reducing evaporation and soil erosion. Improve the porosity of the biological hole loose, fertile, precipitation deep, breathable and good for the roots to create a relatively good living environment, root easy to tie, so that crop growth and yield increase.
