Autumn peanut cultivation experience sharing: master these planting key points
The peanut yield per unit in China's production areas is relatively low, the economic benefit for farmers is not high, and this suppresses the development of the peanut industry. In the southern provinces of China, farmers can increase their income by planting two crops a year in spring and autumn. Based on many years of practical experience, the author summarizes the high-yield cultivation techniques for autumn-planted peanuts

Peanut Seed Storage Methods and Key Technical Points
First, before storage, the seeds must be thoroughly sun-dried so that the seed moisture content drops below 8%. According to experiments, when the seed moisture content is below 8%, storage is very safe, and even at -25°C, germination capacity is not affected. When the seed moisture content is above 10%, respiration increases, releasing

Detailed Explanation of Key Points for Rice Viral Disease Prevention and Control Technology
The occurrence of rice viral diseases is characterized by outbreaks, intermittency and migration. The severity of rice viral disease occurrence is closely related to the farming system, the population and migration patterns of transmission vectors, climatic conditions and cultivation management measures. Control should implement the principle of prevention first, integrated control

Detailed Explanation of Cultivation Points for the Late Growth Stage of Rice
Pest and disease control: Diseases: The main disease requiring attention in the late growth stage of rice is rice blast. After rice heading, seize the opportunity to apply pesticide 2---3 times, with an interval of about 7 days. Apply about 100 grams of tricyclazole wettable powder per mu, mixed with 30 kg of water for foliar spraying.

Control Methods and Technical Key Points for Rice Bakanae Disease
Symptoms: After rice is infected with bakanae disease, the internodes of the affected plants elongate, growing thin and tall, the plant color is paler, the leaves are narrower than those of normal plants, there are varying numbers of adventitious roots inside or outside the leaf sheaths at the nodes, and white mold grows inside the rice stalks, later turning light red, sometimes

How to prevent and control rice purple sheath disease? Practical methods and key technical points
Symptoms After rice heading, dense pinhead-sized purple dots appear on the leaf sheath of the flag leaf, then gradually spread to most of the leaf sheath or the entire leaf sheath turns purplish-brown, especially obvious on the outer wall of the leaf sheath, sometimes infecting the inner wall or reaching deep into the stem. In severe cases, the flag leaf dies 7-10 days early.

Key Technical Points for Field Management of Rice During the Green-Returning and Tillering Stage
The green-returning and tillering stage of rice refers to the period from transplanting to the time before jointing and booting. This period is important for determining the number of panicles and laying the foundation for panicle and grain development. The main goal of field management is to promote good root development, rapid green-returning, and early tillering, and to form sufficiently strong

What are the key management points during the grain-filling stage of rice?
The grain-filling stage of rice is the critical period that determines yield. Field management should aim to nourish the roots and protect the leaves, prevent premature senescence, improve photosynthetic efficiency, promote grain filling, and increase the seed-setting rate and grain weight. 1. Supplemental application of grain fertilizer: apply grain fertilizer according to the seedlings, the field, and the weather. Apply it when the leaf color is on the yellowish side and the flag leaf is short and small; do not apply it when the leaf color is deep green and the flag leaf is large and plump. Apply it to lean fields, not to fertile fields; apply it when there are many sunny days, not when there are many cloudy and rainy days. Generally, it is appropriate to apply 2-3 kg of urea per mu at the booting stage.
