Control Methods and Technical Key Points for Grape Downy Mildew
Control methods: 1. Remove fallen leaves and diseased branches, bury them deep or burn them. 2. Timely pinch off growing tips, prune, drain and weed, and apply more phosphorus and potassium fertilizer. 3. At the early stage of the disease, that is, after July, apply chemicals as soon as slight lesions are seen on the underside of leaves. The chemicals include: Pubo, Ridomil, Sandofan, metalaxyl, Shuangmeiyitejing, etc., used alternately, spraying 4 to 5 times in a row...

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.

How to manage spring early-maturing eggplant during the fruiting period? Practical technical key points
For eggplants grown in spring under plastic film low tunnel cover, from flowering to fruit harvest, under suitable conditions it takes about 18-25 days, and the initial harvest period of the first fruit (door eggplant) is in early to mid-May. During fruit growth, the weather has already turned warm, so the film can be fully uncovered during the day to give the plants plenty of light, but it must be covered well again in the evening. If the nighttime temperature...

Detailed Explanation of Key Technical Points for Spring Management of Loquat
(1) Land preparation: When building a loquat orchard on flat land, planting trenches should be dug, generally 0.80-1.0 m wide and about 0.80 m deep, with the distance between planting trenches generally about 3 m, and the length of the planting trenches determined by the size of the orchard plot or the length of the slope. When digging the trenches, place the topsoil and subsoil separately, with the topsoil placed on the upper edge; when backfilling, backfill the topsoil first, and divide it into 3-...

High-Yield Fertilization Methods and Key Technical Points for Sesame
(1) Land preparation: Sesame seeds are small, the root system is weak, and seedlings grow slowly, so fine land preparation is one of the important measures for achieving full emergence and strong seedlings from a single sowing. Sesame is afraid of waterlogging; in low-lying and rainy areas, on the basis of plowing and land preparation, ditches should be opened and raised beds made to do a good job of drainage and waterlogging prevention. In the urban area of Tianjin, spring rain and snow are scarce, so for spring-sown sesame, winter plowing and harrowing should be carried out...

A Complete Analysis of the Key Technical Points for Sesame Cultivation and Management
Most farmers believe that sesame is a low-yielding, drought-tolerant crop that requires only extensive management. As a result, for many years the yield of spring sesame has been less than 150 kg per mu, and the yield of summer sesame or intercropped sesame has been below 100 kg per mu. Experiments have proven that as long as good seed is combined with good methods and cultivation measures are improved, sesame yields can be increased by more than 20%. 1. Applying...
