我省约有二千万亩旱薄低产麦田,占全省麦田面积的将近一半,主要分布在黑龙港流域。如何种好旱薄地小麦,对实现均衡增产有重要意义。旱薄低产麦田的生产特点:一是水利条件差。无水或少水,主要靠自然降水形成产量。据统计,7—9月降水量和产量关系十分密切,一般每增加100mm 可增产12.3%;二是地薄肥少,普遍缺氮缺磷,盐碱地面积大;三是作物布局和生产水平不适应,复种
About twenty million mu of dry and low yield wheat fields in our province are accounted for nearly half of the province’s total area of wheat fields, mainly in the Heilongjiang River Basin. How to grow dry wheat, to achieve a balanced production is of great significance. Drought thin low-yielding wheat production characteristics: First, poor water conditions. No water or less water, mainly by natural precipitation to form a yield. According to statistics, between July and September precipitation is very close to the output, generally increasing 12.3% for every 100mm increase; secondly, it has less land thinner and fertilizer, generally lack of nitrogen and phosphorus and large area of saline-alkali soil; third, crop layout and production level are not suitable , Multiple cropping
