How to grow yam for high yields? New methods help you increase production
1. Shallow topdressing and skillful watering: When fertilizing, apply into the shallow soil layer so the yam roots can absorb it. Shallow topdressing or less topdressing can both ensure high yam yields. Yam fears waterlogging but should not be too dry either; if too dry, it will seriously affect the swelling of the yam. Spray New High Lipid Film to reasonably match water and fertilizer distribution. 2. Build sturdy trellises: After seedlings emerge, set up trellises in time...

Yam Pest and Disease Control Methods and Key Technical Points
I. Anthracnose. Yams are prone to anthracnose during hot, rainy seasons, and after onset it causes stem blight and leaf drop. In the early stage, black spots appear on the leaves; in the later stage, the leaf color turns black, and the lesions become water-soaked; in severe cases it affects plant growth and causes reduced yield.

Key Technical Points for Integrated Pest and Disease Control in Chinese Yam
I. Agricultural Control 1. Selecting disease-resistant varieties is an effective method for controlling Chinese yam pests and diseases. When cultivating disease-resistant varieties, rational layout is necessary, rotating varieties every 2 to 3 years, and attention should be paid to variety purification and rejuvenation. 2. Crop rotation can reduce or avoid damage from Chinese yam stem rot and root-knot nematodes. Rotate at least once every 3 years with crops that are not infected, such as corn (2343, -3.00, -0.13%), wheat, radish, and watermelon; in old areas where Chinese yam is cultivated year-round, rotate once every year; where conditions permit, paddy-upland rotation can be implemented for better control results.

How to increase the fruit set rate of apricot trees? Master these technical measures
1. Choose superior varieties. Choosing varieties with a high percentage of perfect flowers, strong self-fruitfulness, frost resistance, a later blooming period, and early bearing and high yield as the main planted varieties is the key to increasing the fruit set rate. For example, Jintaiyang, Kate apricot, etc. In addition, varieties with early, mid, and late ripening can also be chosen in combination to reduce losses caused by early spring frost...
