随着复种指数的提高,肥料成为农作物持续高产的突出矛盾。增产必须增肥。我们除了千方百计广辟肥源外,还狠抓稻田套种绿肥,提高鲜草产量,达到既充分用地,又积极养地,不断提高土壤肥力水平。 这里,稻田套种红花草已有很久历史,过去鲜草产量只有2—3千斤。近几年由于我们狠抓关键措施,产量上升到3—4千斤。红光大队900多亩红花草,亩产都在6000斤以上。从红光等大队稻田套种红花草的实践中,认识到红花草有不耐干旱、又忌水涝的特点。要获得红花草高产,抓好播种质量和早期管理是个关键。
With the improvement of multiple cropping index, fertilizer has become the prominent contradiction of continuous high yield of crops. Increase production must increase fat. In addition to doing everything possible to expand our supply of fertilizers, we also pay close attention to intercropped green manures in paddy fields and increase the output of fresh grass so that we can not only make full use of land, but also actively raise land to continuously raise the level of soil fertility. Here, intercropped red flowers have long history of paddy grass, pasture production in the past only 2-3 kilograms. In recent years, as we pay close attention to key measures, the output has risen to 3-4 kilos. Red brigade 900 acres of red flowers, per mu in more than 6000 pounds. From the practice of intercropping red flowers in the paddy fields such as the Red Brigade, it has been realized that the red flowers have the characteristics of being impatient with drought and avoiding waterlogging. To get high yield of red flowers, do a good job sowing quality and early management is a key.
