旱地农业就是最大限度利用自然降水,并运用综合农业技术措施,实现旱地水种、一年多作、一膜多用,提高总体增产效益。据3年试验、示范结果,不管在旱年、涝年、均可实现稳产、高产。每亩地一年可收获小麦202.5～290公斤,皮棉40～53公斤(花生125～190公斤),绿豆40～75公斤(玉米150～270公斤)。如果以0.25公斤皮棉和0.5公斤绿豆分别折合成小麦1公斤计,则小麦亩产比原来常规种植法提高1.5倍,单位降水量(1毫米)的增产效果可提高到0.815～1.165公斤,亩产值由原来的114～144元,增加到361.5～536元。一、旱作覆盖节水型技术 (一)整地起垄覆盖阶段夏末秋初时节,抓紧整地,结合深翻(深松)浅耩,亩施有机肥5000公斤以上,分层施碳铵50公斤、硝铵20公斤,磷肥75～80公斤,然后起垄盖地膜。以 Dry land agriculture is to maximize the use of natural precipitation, and the use of integrated agricultural technology measures to achieve dry land water species, more than a year for a film with a multipurpose to increase the overall efficiency of production. According to the 3-year trial and demonstration results, both stable and high-yield can be achieved no matter in dry years or flood years. One year per acre of wheat can harvest 202.5 to 290 kilograms of wheat, lint 40 to 53 kilograms (peanuts 125 to 190 kilograms), mung beans 40 to 75 kilograms (150 to 270 kilograms of corn). If 0.25 kilograms of lint and 0.5 kilograms of mung beans are respectively converted into 1 kilogram of wheat, the yield per hectare of wheat will increase 1.5 times than that of the conventional planting method. The yield per unit of precipitation (1 millimeter) can be increased to 0.815-1,165 kilograms per mu From the original 114 ~ 144 yuan, increased to 361.5 ~ 536 yuan. First, dry-cover water-saving technologies (A) covering the ridge Ridge cover the beginning of summer and fall of early autumn season, pay close attention to the formation, combined with deep plowing (deep pine) shallow 耩, Mushi organic fertilizer 5000 kg above, Kg, ammonium nitrate 20 kg, phosphate fertilizer 75 ~ 80 kg, and then cover the plastic cover.
