Main cultivation technical points for purple sweet potato planting
1. Land selection: Most purple sweet potatoes belong to mid-to-late maturing varieties, with tuber rapid expansion and yield formation occurring relatively late. The plot to be planted not only requires relatively high soil fertility, but the soil texture should be light loam or sandy loam, and the land levelness and drainage and irrigation conditions should be good. Purple sweet potato has

Key Field Management Techniques for Growing Vegetable Sweet Potato
1. Checking seedlings and filling gaps: 5-7 days after planting, check the survival of the sweet potato vines and promptly replant strong seedlings in spots where plants are missing. 2. Topdressing: For spring sweet potatoes, 30-40 days after planting, after the vines spread and before the rows close; for summer sweet potatoes, 20-25 days after planting, open holes below the side of the ridge and apply topdressing, using 30 kg per mu of compound fertilizer (N:P:K=10:7:8); combine topdressing with loosening the soil between ridges and hoeing weeds.

Detailed Explanation of Key Techniques for High-Yield Cultivation of Hybrid Rice
1. Seedling Raising (Dry Seedling Raising Technique) 1. Seed treatment and germination acceleration: Before soaking the seeds, sun-dry them for 1-2 days, rinse with clean water, remove the empty and shriveled grains, and put the seeds in a nylon mesh bag. Then soak the seeds in a 500-fold dilution of 50% carbendazim wettable powder for 24 hours, take the seeds out, wash them clean with clean water

Key Points of Fertilizer and Water Management Techniques for High-Yield Rice Cultivation
In high-yield rice cultivation, the level of yield is determined by fertilizer and water application as the core; fertilizer and water application should be decided according to the fertilizer requirements of the variety, the level of soil fertility, the planting time, etc. Generally, 100 kg of paddy rice requires 2 kg of pure N, 1.2 kg of pure P, and 1.5 kg of pure K. The fertilizer and water application measures are specifically proposed as follows:

Key Cultivation and Management Techniques for Machine Transplanted Rice
1. Field Ploughing and Preparation Requirements 1) Field ploughing and preparation: rotary tillage depth of 10-15 cm; plough tillage depth of 15-20 cm. 2) Field levelling: the surface height difference within each field block shall not exceed 3 cm. The field surface shall be basically free of weeds, debris, shallow stubble and other residues.

Field Management Techniques for Rice During the Jointing and Panicle Elongation Stage
Rice jointing begins around the peak tillering stage and internode elongation does not stop until several days after heading; in production, this period is called the jointing and panicle elongation stage. The field management goals during the jointing and panicle elongation stage are: on the basis of preserving tillers and increasing panicles, promote strong stems and large panicles, and prevent excessive vegetative growth

Integrated Control Methods and Techniques for Rice Stem Borer Damage
Integrated control technology for stem borer damage refers to addressing the adverse conditions of residual toxicity, resistance, and resurgence caused by long-term pesticide application against rice stem borers, minimizing harm to humans and environmental pollution while earnestly implementing the plant protection policy of "prevention first, integrated control," persisting in carrying out pest and disease forecasting

High-Yield Peanut Cultivation Techniques and Disease Control Methods
I. Bacterial Wilt of Peanut This disease mostly occurs from the seedling stage to the peak pod-setting stage of peanut. Spring peanuts are affected from May to June, and summer peanuts from September to October, with a relatively severe incidence rate. In infected plants, the top leaves first become soft and droop, then the leaves of the whole plant wilt and hang down, but the wilted leaves can still remain green

Key Techniques for Plastic Film Mulch Cultivation of Spring Peanuts
The plastic film mulch cultivation technique for spring peanuts is one of the "Top Ten" advanced agricultural technologies promoted by the Ministry of Agriculture. It was introduced to our city for trials in 1998 and began demonstration and extension in 1999. Years of practice have proven that this technique is indeed an important measure for improving peanut yield and quality.
