2, pay attention to drainage: timely drainage after the rain stains to prevent rot.
3, tree cover: cover the straw to reduce evaporation, etc., to keep the soil loose, stabilize the soil temperature, promote new roots.
Second, soil, fertilizer, water management
1. Soil Management: The soil is the basis for the growth of fruit trees. Red-fruited pomelo can grow well in the soil with a pH of 5.5-6.5.
Weeding and weeding: One month after planting, we combine irrigated fertilizer with a total of one cultivating in the entire garden, combined with fertilization and intercropping and then cultivating 2-3 times.
Deep-turning and soil improvement (optional, conditional): According to climatic conditions and root activity time, the soil is deep-rooted during the summer-autumn season in May-June or October-November.
Planting green manure and intercropping crops: Using gaps, interplanting green manures such as peanuts, beans, watermelons, and bitter radishes, effectively using land and sunlight, gardening and gardening, using short growing lengths, reducing surface erosion, increasing soil organic matter and nutrients , fertilize fertility. However, it is not possible to plant high poles and Teng crops.
Cultivate soil: in winter, Zhupei pond mud or gully mud, soil 1-2 guarantee warmth and antifreeze, improve soil.
2, timely fertilization
In the later years of the year, it was mainly to promote the growth and development of saplings and to extract strong shoots to form quickly. Fertilization is mainly based on nitrogen fertilizer, with phosphorus and potassium fertilizers. From the 20th day after planting, that is, before the shoot is sprouted, thin fertilizer is applied once every 10-15 days, and about 5-6 times is applied at the beginning of July.

Take the method of pulling, supporting, etc. to form a natural and happy tree, and leave it to the ground by going to zero. Keep the Qi early, unify, and shorten the length of the tree crown as soon as possible. After the pruning, apply a “wound and anti-corrosion film†to protect the wound.
IV. Main diseases and pests and their control

With 10% wok Kuning 1000 times plus 700 units of agricultural streptomycin and 10% of the lime sulfur spray each time, anti-ulcer disease.
From June to July, 800 times of water used for amine phosphorothiophene, 3000 times of kungfu, and 600 times of thiophanate-methyl were sprayed 2-3 times to prevent fleas and moths.
8-10 months with thiophanate + enemy killed + acaricide, etc. sprayed 2-3 times, anti-leaf leaf moth Tianni and so on.
In November-December, he used the "General of Tree Guards" + Bordeaux mixture to spray 1-2 times.
V. Cold and Frost Protection and Clear Garden
1. Cold and frost-proof: water spray, earth-cultivation, grass-covering, film-covered smoke, use the “General Tree Protector†emulsion to spray the trunk, keep it warm and prevent freezing, and protect the tree for safe wintering.
2. Qingyuan Garden: Cut off the dead branches, remove the defoliated weeds and burn them centrally or bury them deeply. Then spray the “General Tree Guard†on the garden to kill the virus and seal the garden.
