Detailed Explanation of Spring Management Measures and Technical Points for Lychee
China generally experiences dry climate, which promotes nutrient accumulation and flower bud differentiation in lychee and longan. It is currently spring, and lychee management during this season is a key link related to the quality of growth and development in the current year. Based on the current growth and development situation of lychee and longan, the following technical work opinions for spring management are specifically proposed. Lychee due to...

Key Technical Points for Fruit Retention and Fruit Enlargement in Lychee, Longan and Mango
At present, most lychee and longan trees in Guangdong Province are at the stage from flower panicle emergence to flower bud stage. Affected by the weather since the beginning of spring, with relatively high temperatures and suitable humidity, the flower panicles of lychee and longan have emerged early, pests and diseases have occurred early, and the base of pest and disease sources after winter is relatively high. It is expected that the main pests and diseases during the flowering period of lychee and longan will occur at a moderate level, with some areas being relatively severe. Lychee stink bug...

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. Control: In the early stage of the disease, spray once every 7 days with 50% Tuzet 600x solution, or 7...

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.

Technical key points for timely and proper pollination of apricot trees
Why do apricot trees often bloom profusely but rarely bear apricots? The main reason is poor pollination. To improve the fruit set rate of apricot blossoms, preparations must be made in advance and apricot blossom pollination must be done promptly, carefully and meticulously. For the main cultivars of apricot trees, choose varieties with natural pollination ability, a low rate of abortive flowers and a high natural pollination fruit set rate...

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...

Detailed Explanation of Key Technical Points for Flower and Fruit Management of Apricot Trees
I. Artificial Pollination Apricot trees rely on bees and others for pollination. But experience shows that carrying out artificial supplementary pollination can increase the fruit-setting rate by 3-4 times compared with natural pollination. Artificial supplementary pollination should be carried out during full bloom, because the apricot flowering period is very short (5-7 days), so preparations should be made in advance. Apricot flower stalks are fragile and break easily, so extra care should be taken during pollination...

Detailed Explanation of Yam Planting Methods and Technical Key Points
Yam, also known as shanyao or Chinese yam, is a perennial twining herb. Traditional Chinese medicine holds that yam has multiple effects such as strengthening the spleen, tonifying the lungs, consolidating the kidneys, and boosting essence. As a highly nutritious food, yam contains large amounts of starch and protein, various vitamins, glucose, crude protein amino acids, choline, allantoin, and more. Among these, an important...

Key Technical Measures for Renovating Low-Yield Apricot Orchards
I. Characteristics of Low-Yield Orchards Low-yield orchards include low-yield young orchards and low-yield old orchards. An apricot orchard whose yield is lower than the average yield of the region for consecutive years, or lower than that of similar surrounding orchards, is considered a low-yield orchard. 1. Young orchards in full fruit stage show weak tree vigor, small and slow-expanding canopies, low branching of extension shoots, and fine and weak fruiting branches...
