Rice is the main food crop in China, and there are many people planting. So, do you know that the influence of rice growers affects rice yield? What do we need to pay attention to during the planting process? The following small series will tell you about it. What are the factors that affect rice yield and quality? 1. Improper breeding methods The methods of fault breeding that affect rice yield and quality include: (1) The amount of sowing changed from thin to dense: at that time, a single cultivated household cultivated nearly 0.5kg of buds per square meter, and the cultivated amount doubled compared with the normal cultivated amount, causing the seedlings not to start on the trampoline, and the seedlings Too thin, stems become round rather than flat, and the internodes are long and too thin, affecting the yield per unit of rice yield and quality. (2) Change from dry seedling to water seedling: Dry seedling refers to healthy rice seedlings cultivated in dry soil with good soil. However, some cultivated households cannot implement dry seedlings due to various reasons, and can only use water fields to raise seedlings. However, the paddy soil is stiff and cool, which is not conducive to the growth of rice roots. It can lead to short roots, few roots, thin roots, weak roots and less white roots, which makes the seedlings slower and less grow at the seedling stage. It has a great damage to the development process of rice, and thus cuts the output value. 2. Transplant density is too dense The said transplant means that the plant spacing should be 9 inches × 4 inches or more when transplanting. At that time, rice was promoted by wide and narrow lines. Generally, the two specifications (10 inch x 8 inch) x 6 inch and 12 inch x 6 inch are used. The intention is to make the rice fully divided, so as to meet the demand of 550 to 600 ears per square meter, but now the situation of dense planting It is ubiquitous, but it is densely planted. Rice can not be divided into millet. It can only rely on the main ear, and the high yield of the previous rare plant is changed to the dense planting and maintenance at that time, which greatly reduces the output value. 3. Fertility imbalance Generally, medium fertilizer, 500kg per 667m2 of rice, should be 1000-1500kg of farmyard manure, 3-5kg of potassium sulfate, 10-15kg of phosphoric acid, 15-20kg of urea, but according to statistics, only a single grower The amount of fertilizer reached this standard, some cultivated households did not even need agricultural fertilizer and potash fertilizer, and some cultivated households only had sufficient nitrogen fertilizer, and the amount of phosphate fertilizer was small. This resulted in the imbalance of potassium, phosphorus and nitrogen in the farmland. Poor absorption. In addition, the single cultivated household only topdressed without applying the base fertilizer, and the fertilizer was not used reasonably, but the root layer of the deep nitrogen layer of the surface layer could not be absorbed, and it was easy to evaporate, which could not meet the intention of the whole layer of fertilizer, and thus affect the output value of rice. 4. Improper management measures The fault handling method affecting the output value of rice: (1) Turning the ground: The depth of the roots cannot reach the depth required for the growth of rice roots. (2) Moisture handling: The demand for normal development of rice has not been reached in the control of water volume and water delivery time. (3) Pests and grass control: After planting rice for many years, the field will hide various germs, and more grasses and pests will have certain resistance to various pesticides used every year, so they cannot cure those diseases. Insects and grass damage, which in turn affect the output value of rice. There are many factors affecting rice yield and quality. Among them, field management is very important. The above are the detailed factors and solutions affecting rice yield and quality, and I hope to help farmers.
