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

How to Prevent and Control Sweet Potato Stem Nematode Disease? Detailed Technical Methods
Sweet potato stem nematode disease is a devastating disease in sweet potato production. It is highly destructive and spreads quickly. It can infect and cause damage during the seedbed stage, field stage, and storage stage, but it mainly infects the tubers. Affected sweet potatoes have brown, bluish skin with cracked patterns, and the tubers are light. Some tubers show no external abnormalities, but are hollow and pithy inside. This disease not only affects the quality of sweet potatoes, but also severely affects sweet potato yield.

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

High-yield cultivation experience and key technical points for cassia seed
1. Growth habits: Cassia seed prefers a warm and humid climate, is not tolerant of cold and fears frost, but has low soil requirements; it can be planted in sandy soil and clay soil, and grows best in slightly alkaline soil. When planted in well-drained, loose and fertile soil, the root system is well developed, with the most nitrogen-fixing root nodules.
