Key Field Management Points 5-7 Days Before Transplanting for Dry-Raised Rice Seedlings
As one of the rice industry demonstration county projects, Dapai Village, Shangguan Town, Dali City, has a rice area of 1425 mu this year, with a yield target of 750 kg/mu. To achieve high and even higher rice yields, agricultural technicians at both the city and town levels have gone into villages and households, gone deep into the fields, and earnestly guided

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 Points for Early-Stage Cultivation Management of Rice in Paddy Fields
As the saying goes, "three parts planting, seven parts management." After rice transplanting, it enters the paddy field management stage, and whether management techniques are in place has a great impact on per-unit yield. The core of early-stage cultivation management in paddy fields is "applying tillering fertilizer heavily and early." This can promote early and rapid growth of seedlings, ensure early formation of effective tillers, and lay the foundation for high yield.

Key Technical Points for Off-Season Cultivation of Sweet Potato
In order to improve the economic benefits of growing sweet potatoes, in addition to post-harvest deep processing, sweet potatoes can also be brought to market earlier through off-season cultivation. Two off-season cultivation techniques are introduced here. 1. Cultivation technique for sweet potatoes marketed in May-June: Use the method of storing water between ridges inside a greenhouse plus a small arch shed to improve the heat preservation effect. Planting can be done from December to January of the following year. Using virus-free shoot-tip seedlings cultivated in a small arch shed, the yield for market in May is 1300 kg per 667 sq m. The income is much higher than that of conventional planting.

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

Sweet Potato Protected Cultivation Experience and Key Technical Points
Using large and medium shed facilities for early-maturing sweet potato cultivation can not only improve the utilization rate of limited land resources and light-heat resources and increase the yield and benefits of sweet potato production, but also enable double-season sweet potato cultivation in the Beijing suburbs, promoting reform of the cropping system

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.

Control Methods and Technical Key Points for Sweet Potato Brown Spot Disease
Sweet potato brown spot disease, also known as angular leaf spot. [Pathogen scientific name] Cercospora batatac Zimm [Host crops] Sweet potato, water spinach, morning glory, etc. [Disease diagnosis] It mainly damages leaves. When leaves are affected, water-soaked small spots first appear, then the lesions gradually expand

Key Technical Points for Soil Testing and Formulated Fertilization in Sweet Potato Cultivation
1. Fertilizer requirements: Of the three major elements nitrogen, phosphorus and potassium, sweet potato has the greatest demand for potassium, followed by nitrogen, then phosphorus. Sweet potato likes potassium, and increasing potassium fertilizer has a clear effect on both yield and quality. Sweet potato absorbs few nutrients at the seedling stage; from the branching and tuber-setting stage to the vigorous stem and leaf growth

Five Key Points for Late-Stage Sweet Potato Management to Ensure a Bumper Harvest
After late August, summer sweet potatoes enter the critical period of tuber expansion. At this time, management should be strengthened. On one hand, the nutrients needed for tuber expansion should be met to the greatest extent possible; on the other hand, premature senescence of stems and leaves should be prevented, photosynthesis should be enhanced, and nutrient accumulation should be increased. Specific yield-boosting technical recommendations are as follows
