红花草是主要绿肥之一。不仅成本低,效果大,而且对改良土壤具有一定的作用。我场历年种植12,000余亩,占稻田播种面积的80％以上,但单产低,亩产鲜草仅3680斤,亩产草籽61斤。为了提高红花草产量,促进水稻增产增收。近两年来,我场采用不同的肥料和用量进行试验,结果亩产鲜草量由3680斤提高到4717斤,增产1037斤,增产28％,产籽量由61.11斤提高到70.56斤,增产15.46％,提高了产量,增加了经济收入。现将试验小结如下: 一、试验情况 1、试验基地 土质粘壤,pH6,排灌方便,田面平整,雨停地干,不渍水,为红 Red flowers are one of the main green manure. Not only low cost, great effect, but also to improve the soil has a certain role. Over the past 12 years, I have planted more than 12,000 mu of land, accounting for more than 80% of the sown area in paddy fields. However, the yield per mu is only 3680 kg per mu and 61 kg per mu. In order to improve the yield of safflower, promote rice yield increase. The past two years, my field using different fertilizers and the amount of testing, the results of fresh yield per mu from 4,680 pounds to 4,717 pounds, an increase of 1,037 pounds, an increase of 28%, the output of seeds increased from 61.11 pounds to 70.56 pounds, an increase of 15.46 %, Increased production, increased economic income. Now the test summary is as follows: First, the test conditions 1, test base soil clay, pH6, irrigation and drainage convenience, field surface formation, dry rain stop, no water, red
