Key Techniques of Rice Field Planting Sowing Red Grass
Saffron, also known as Ziyunying, is a winter green manure crop commonly cultivated in our county. It is rich in organic matter and nitrogen, can improve soil physical and chemical properties and fertility, and lays a good foundation for crop cultivation for yield and stability. The cultivation techniques for nesting Ziyunying in rice fields are described as follows: First, do a good job sowing quality, ensure that the pre-winter seedlings 1. Seed treatment: Saffron should use the seeds of the current year, and the seed amount is generally 2 kilograms per acre. Sowing before sowing, if you use fine sand, you can speed up the germination rate. 2. Field preparation: Timely 2-3 days before sowing, “Happy Valley Waterâ€, sowing water after draining. 3, timely early sowing: general safflower in the frost before the 30-40 days of growth, growth more than 3 branches, the ability to resist cold can be strengthened. Therefore, the sowing date should be controlled around September 25-28 (ie, 15-20 days before the harvest of two nights). 4, sowing quality: First, to ensure that the number of basic seedlings, to ensure that the sowing rate per acre of not less than 2 kg; Second, with fertilizer sowing, require phosphorus seed dressing, that is, after the seeds with rice soup and wet after the use of calcium magnesium phosphate seed dressing Immediately after sowing; Third, we must promptly cover, after cutting, but also when the field is wet, sprinkle a thin layer of stalks (thin to be light) to cover the seedlings, machine harvested rice fields, to promptly bundle into a pile of 禾Spread the stalk or move it out of the field to avoid crushing the green manure seedlings. Second, strengthen field management and increase green manure production 1. To coordinate the symbiosis between rice and rice: after sowing, paddy fields should be filled with “running water†to ensure the water requirements of rice and fertilizer, and to effectively prevent waterlogging. 2. Timely ditching: Safflower and weeds are resistant to wet spots. Immediately after the two days of harvest, we should open the ditch and clear the ditch system so that the ditch can communicate with each other and the water flow can be unimpeded. 3. Applying good winter fertilizer: Appropriate amount of phosphorus and potassium fertilizer applied in the seedling stage before winter can play a role in increasing phosphorus by nitrogen, keeping seedlings and freezing, and achieving the effect of raising small fertilizers and large fertilizers; if it applies 10 kg of urea per acre after opening springs, Potassium chloride can significantly increase the yield of green manure. Third, timely returning the land to farming, give full play to the fertilizer effect Saffron green manure leaves are tender, easy to plow, decay quickly. The returning time should be controlled from flowering to initial stage. Immediately after the pressure is poured, water is accelerated, the decomposition is accelerated, the utilization of green manure is increased, the yield of early rice is increased, and the quality of rice is optimized.
