Teach you to plant good red flowers
"One year of red flowers and three years of field feet." Green manure has always been China's fertilizer "national treasure." Saffron (Ziyunying) is an important source of organic fertilizer for rice fields in our province. It is not difficult to plant good red flowers. As long as you master the following technical points, you can win high yields. Timely early sowing: Timely early sowing is the key to the early occurrence of safflower seedlings and their ability to win more branches before the winter. Therefore, it is advisable to plant the double-cropping paddy field before and after the autumn equinox, but not later than National Day. In the first-year paddy field, it is best to plow till the sowing time can be advanced 5 to 7 days before the equinox. The sowing rate per acre should be 2 to 2.5 kg, and the amount of seed used for late sowing and poor fertility should be increased to 3 kg per mu. Mixed sowing can improve the output of green manure. In the double-cropping paddy field after sowing of red safflower, 100 grams of rapeseeds and 250 to 300 grams of garden flowers are planted 10 days before harvest, and red-crop seeds can be sown with other seeds at the same time. It is also possible to mix some broad beans with iron hoe after harvesting the late rice. Reasonable irrigation and drainage: The grass planted in the plate field, after the harvest of the late rice, it is necessary to open a good ditch in time, so that the gutter, gutter, and gutter can be matched, and the ditch can communicate with each other, and there is no water in the field. In case of drought in autumn and winter, the horse water should be timely filled once, and it should be drained in time in spring. Scientific fertilization: The fertilization of grass should be based on phosphorus and potash fertilizers. Phosphorus fertilizer in addition to fertilizer, in the winter before every acre should also be followed by 25 kg of calcium magnesium phosphate fertilizer. Before and after the beginning of the spring of growing up, 7 to 8 kilograms of ammonium bicarbonate per acre is used to pour 10-15 kilograms of biogas slurry. Cover grass antifreeze: Although the red flowers are more cold-resistant, but below -3 °C will also suffer from frost damage. The effective method to prevent freezing damage is to harvest the late rice, harvest the field with high rice piles, or evenly cover half of the straw in the field of late rice. Chemical weeding: grass fields can easily grow to see Aegice (Lobula grass), hindering the growth of Saffron, and even cause grass shortage. The prevention method is: When looking at A. mellifera 3.5 leaves, select sunny, use 12.5% ​​per acre with 40 ml of gauze-near emulsion, 40 to 50 kg of water, evenly spray, with a significant weeding effect, absolutely safe for safflower. Timely Wowo: "Earth is early, Gu Yu is late, before and after the Ching Ming is timely," a flower to spend two sets of flowers is the appropriate period, generally in the end of March to early April. After ploughing, the grass exposed outside the plough blank should be stepped into the mud to accelerate the decay.
