几年来,胶东地区的广大农民,在科研部门的协助指导下,发挥自己的聪明才智,在开发利用旱薄地发展粮食生产上大作文章,取得了较为理想的效果,并积累了一些经验。开发旱薄地,发展大沟麦生产,其优点如下: 一是效益高。改过去的单一种花生、地瓜的一年一收为一年两收,赚了小麦收入。二是产量理想。这些旱薄地过去种直播小麦,风调雨顺时亩产在100公斤左右。如果春旱缺雨,产量很低,有时甚至“连种也打不回来。”改大沟麦种植,基本保收,亩产一般在150公斤左右;在土质条件较好,有一定水浇条件的,亩产可达300公斤以上,最高产量可达646.45公斤。三是充分利用了优势。这个优势包括地力优势、边行优势和地墒优势。地力优势:因种植大沟麦垄行 Over the past few years, the vast number of peasants in the Jiaodong region, under the guidance and assistance of scientific research departments, have given full play to their wisdom and made great contributions in the development and utilization of drylands in food production. They have achieved satisfactory results and accumulated some experience. The development of dryland, the development of large ditch wheat production, its advantages are as follows: First, high efficiency. To change the past, a single kind of peanut, sweet potatoes a year received a two harvest a year, making wheat income. Second, the output is ideal. In the past, these dry-type live direct broadcasts of wheat produced about 100 kg of mu per month when the weather was favorable. If the spring drought, the yield is very low, and sometimes even “can not even call back.” Change the ditch wheat planting, the basic income, per mu is generally about 150 kg; in the soil conditions are good, there are certain conditions of water Of the mu produce up to 300 kilograms, the highest output up to 646.45 kilograms. Third, make full use of the advantages. This advantage includes the advantages of geo-power, edge and moor. Geographical advantages: due to the planting of large ditch Makorou line
