矮秆齐春大麦,系1965年从丹麦引入,经连续几年选育而成,一般亩产700—800斤,自推广以来,很受欢迎。但近年发现,品种已有混杂退化现象。为提纯复壮,争取高产,现将种好管好矮秆齐春大麦应注意的一些问题,介绍于下: 播种前后:播前要细致整地,有灌溉条件的要做好沟畦,以利灌溉。播种宜早,一般2月下旬至3月初,解冻3—4寸深即可播种。早播可使幼苗经低温锻炼,生长墩实,为高产打下基础。播种深度,一般1—1.5寸,土壤干旱可播到2寸深。播种过深,幼苗不旺,分蘖力弱。播种量25—30斤为宜。
Short stalk Qi spring barley, introduced from Denmark in 1965, after several years of breeding, the general yield 700-800 pounds, since the promotion has been very popular. However, in recent years, it has been found that varieties have been mixedly degraded. In order to purify and rejuvenate and strive for high yield, we should plant some of the problems that we should pay attention to when weeding dwarf Qi Chun barley. The introduction is as follows: Before and after sowing: . Sowing should be early, generally late February to early March, thaw 3-4 inches deep sowing. Early seeding can make seedlings by low temperature exercise, growth pier, lay the foundation for high yield. Seeding depth, generally 1-1.5 inches, soil drought can be broadcast to 2 inches deep. Sowed too deep, seedling is not flourishing, tillering weak. 25-30 kg sowing rate is appropriate.
