Detailed Explanation of Rice Dry-Raising and Dry-Planting Cultivation Techniques
Dry-raising and dry-planting refers to the practice, when dry-raised early rice seedlings reach the suitable seedling age for throwing and transplanting but the field is dry and lacking water for paddy preparation, of directly spraying herbicide to control weeds, then making holes with a wooden stick or opening furrows with a shovel, and then transplanting the seedlings. Key points of the cultivation technique (1) Paddy field treatment: before planting, spray the paddy field with herbicide to control weeds; options include...

Fertilizer Requirements and Key Fertilization Techniques for Rice at Different Growth Stages
I. Fertilizer Requirements of Rice. Nitrogen, phosphorus, and potassium are the nutrient elements that rice requires in relatively large amounts while soils are relatively deficient in them. Generally, for every 100 kg of rice grain produced, about 1.6-1.9 kg of nitrogen, 0.8-1.3 kg of phosphorus, and 1.8-3.8 kg of potassium are absorbed, with a ratio of approximately 1:0.5:1.3. Nitrogen uptake is highest from the greening stage to the tillering stage...

What is the effect of different fertilizer ratios on rice yield?
When rice shows premature senescence from the heading to the maturity stage, it leads to poor grain filling, an increase in blighted grains, and reduced yield. There are many factors that cause premature senescence in the late growth stage of rice. First, improper cultivation management. If the planting density is too high, the plants grow thin and weak; if too much nitrogen fertilizer is applied in the early and middle stages, while phosphorus, potassium and trace element fertilizers are applied...

Common Problems in Rice Seedling Raising and Countermeasures
Cultivating robust seedlings is the key to high rice yields. By analyzing common problems that arise during seedling raising, corresponding solutions are proposed to provide technical reference for cultivating high-yield robust seedlings. (I) Common problems in machine-transplanted seedling raising and countermeasure techniques 1. Poor seed emergence. Machine-transplanted seedling raising often suffers from poor seed emergence, uneven emergence, and...

Methods and Key Technical Points for Topdressing Potassium Fertilizer on Rice
Topdressing potassium fertilizer on rice can achieve a significant yield increase. Sufficient potassium is beneficial for enhancing photosynthesis, promoting the synthesis and accumulation of sugars, and improving plant resistance. It can also enhance the respiratory capacity of the rice root system, promote the absorption of nitrogen and the synthesis of proteins, making the rice grains large and plump, with high and stable yields.

What are the precautions for rice pest and disease control?
What should be noted when controlling rice pests and diseases? Advice needed. The control target must be clear: take corresponding pesticide control measures according to the different types of pests and diseases in the field. When mixing pesticides, their content must be clearly understood, especially for the control of neck blast; tricyclazole has 2 formulations, and they must not be confused. Do not arbitrarily increase...
