我省是一个粮食大省,小麦生产在我省占有重要地位,近年来,虽然小麦生产较前有了大的发展,但在实际生产中还存在着一定的问题,现就这些问题提出以下对策。一、存在的问题1.整地质量差,播种不科学,造成出苗不好连年旋耕或小拖拉机耕,耕层变浅,土壤容重偏高,耕层紧实,并形成坚硬的犁底层,影响根系下扎,不利于吸收深层养分和水分。耕翻后没耙细、旋耕后不压实麦田,表层土壤过于悬松,透风跑墒,易旱易冻,且造成深播弱苗。
In our province, the province is a major grain-producing province and wheat production occupies an important position in our province. In recent years, although wheat production has made a big development in the past, there are still some problems in actual production. The following countermeasures are put forward on these issues . First, the existing problems 1. Poor soil preparation, planting unscientific, resulting in poor emergence in successive years rotary or small tractor plow, shallow farming, soil bulk density is high, tight tillage, and the formation of hard plow bottom, the impact of Under the root tie, is not conducive to the absorption of deep nutrients and moisture. Tillage did not rake fine, rotary compaction wheat field, the surface of the soil is too loose and loose, ventilation run moisture, drought and easy to freeze, and the deep-seeding weak seedlings.
