Winter wheat is the largest grain crop in the north of China, and it is also the main ration of northern China's residents. In areas such as Henan, Hebei, and Shandong, the yield of wheat in many places has reached more than 600 kilograms, including the “22†wheat variety. Can reach more than 700 kilograms. So, in addition to the high yield of wheat, what factors are related to it? First, prepare before broadcast 1. Soil Fertility Requirements At present, in the main wheat-producing areas of China, the organic matter content of the soil in the tillage layer is not high, and there are two ways to increase the organic matter content of the soil. One way is to return the straw to the field, and the other way is to increase organic fertilizer. 2. Applying basal fertilizer For wheat fields with soil organic matter content above 1.2%, if the expected target yield is 600 kg, it generally requires 3000-5000 kg of fully fermented and decomposed organic fertilizer, or 1,000 kg of decomposed chicken manure. 3. Straw returning straw to the field is an effective way to supplement and balance soil nutrients and improve soil structure. It was determined that 500-700 kg of corn stalks were returned per acre. After one year, the content of organic matter in the soil can be relatively increased. 0.05%-0.15%, soil porosity, can increase 1.5% -3%. 4. The selection of good varieties and good methods combined to achieve the purpose of high yield and stable production. The principle of selecting wheat varieties is to select varieties with strong productivity, lodging resistance, disease resistance and strong resistance. At present, there are many high-yield wheat varieties in China, such as Jimai 22. In production, the most appropriate high-yield species should be selected based on the region's climate, soil, soil fertility, cropping systems, yield levels, and pest and disease conditions. Second, rational farming In recent years, rotary cultivators are commonly used for cultivating farmland in winter wheat regions in China. However, for wheat fields that have been ploughed and ploughed for many years in succession, soil layers less than 15 cm in rotation can easily form a solid plow bottom layer, which is not conducive to wheat. Roots under the bar, is also not conducive to soil water conservation. 1. Precise, semi-precision seeding In order to get high yields from wheat, the quality of the seed is crucial, and it is best to use coated seed, because the special seed coating agent for wheat contains pesticides for disease prevention and pest control. Micro-fertilizers and biological regulators are conducive to the comprehensive prevention and control of pests and diseases and nurturing strong seedlings. After the ploughing, the loosening of the surface soil in the wheat field must be carried out after the planting. Otherwise, the phenomenon of deep sowing will affect the occurrence of wheat tillering. Therefore, after the land is ploughed, it must be promptly hoeed, smashed, and loosened. , Leveling the ground, on the Panasonic real. 2. Watering conditions Watered conditions can be watered 7 to 10 days before the harvest of the previous crop; before harvesting, watering can be done after cultivating and cultivating. When sowing, you can use the wheat precision sowing machine to sow, to ensure that the depth of the sown consistent, consistent spacing, accurate sowing, uniform sowing, strictly control the sowing depth of 3 to 4 cm, sowing depth of more than 5 cm will cause weak seedlings. 100 Feet Photoluminescent Exit Sign Luminescent Signage,100 Feet Photoluminescent Exit Sign,Afterglow Super Sign,Afterglow Tape JINAN REALGLOW CO.,LTD , https://www.realglowsign.com
