Introduction to the four disadvantages of rice Honda management
The main results are as follows: 1. The soaking time of soil preparation is short, bumpy and enlarged, transplanting seedlings without soaking thoroughly, discharging salt and washing alkali is not thorough, it is easy to produce salt damage, which is disadvantageous to the growth and development of seedlings.
2. This year, there are many windy days, cloudy days and large temperature difference, which leads to the seedlings can not be ventilated normally, which is disadvantageous to slow down the seedlings after planting.
3. People are more afraid of water. Transplanting rice seedlings in deep water and deep water management are disadvantageous to raising ground temperature, taking root early, early seedling emergence and early tillering after transplanting.
4. The water storage in last winter and this spring has poor water quality and heavy soil salinity, which makes the living environment of rice disadvantageous.

Four Key Points about Rice Fertilization
First, pay attention to applying enough organic fertilizer. Organic fertilizer contains various nutrients, which can improve soil ventilation and fertilizer absorption and water retention characteristics, promote stable growth of rice plants, and obtain high yield and high quality. Organic fertilizer is mainly used as base fertilizer, 30 - 40 loads of decomposed soil fertilizer per mu, or 30 - 40 kg of cake fertilizer, and 40 - 50 loads of human and livestock manure can be applied before ploughing. Second, attention should be paid to controlling nitrogen fertilizer. Excessive application of nitrogen fertilizer in rice will not only cause increase of ineffective seedlings, turning green, lodging, intensification of diseases and insect pests, but also lead to more empty grains and lower seed setting rate, which will affect rice yield.
