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.

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:

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 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.

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

Detailed Explanation of Key Points for Virus-Free Sweet Potato Cultivation Techniques
Virus-free sweet potatoes differ from ordinary sweet potato varieties, and their cultivation techniques also differ. The cultivation techniques are introduced as follows: 1. Ridging and early planting. Virus-free sweet potatoes have strong drought tolerance and vigorous growth. After the wheat harvest, ridges should be made as early as possible to strive for early planting. 2. Formula fertilization. For dry and infertile land, apply 5000 kg of farmyard manure, 30-40 kg of ammonium bicarbonate, 15-20 kg of potassium sulfate, and 40-50 kg of superphosphate per mu; for medium to above-medium fertility fields, apply 3000-4000 kg of farmyard manure, 20-30 kg of ammonium bicarbonate, 20 kg of potassium sulfate, and 30 kg of superphosphate per mu. In addition to applying sufficient base fertilizer, it is also necessary to apply hole fertilizer, seedling-promoting fertilizer, tuber-promoting fertilizer, and later-stage foliar topdressing, etc.

Prevention Methods for Sweet Potato Cellar Rot and Storage Management Techniques
The biggest problem during sweet potato storage is cellar rot. Once cellar rot occurs, it may at best reduce the quality of the sweet potatoes, and at worst cause all the sweet potatoes in the cellar to rot, resulting in varying degrees of loss. Sweet potato cellar rot is mostly caused by physiological diseases and infectious diseases. Physiological diseases mainly
