The planting time should be 2-3 months before bamboo shoots sprout, and the row spacing should be 3× 4m. When planting, put the topsoil down first, then mix it with manure, sheep manure and other organic fertilizers 15-20kg, and finally consolidate the soil for the weathered layer. When planting, be sure to step on the soil around the roots to facilitate survival, and finally spray the roots with water.
Management method of fertilizer and water Young tree management method: Water young trees every 3-5 days after planting, and keep the soil layer moist all the time to ensure the survival rate. When spring shoots germinate, light fertilizer or 0.2% urea solution can be sprayed, and young trees should be frequently applied with thin fertilizer (small concentration, applied in stages). 2-3-year-old fruit trees should pay attention to two fertilizers at one end, mainly nitrogen, phosphorus and potassium as bedding, and topdressing nutrients such as sodium dihydrogen phosphate and mannitol on the leaves. Cover trees with wheat straw in dry season. In winter, 30-50 kilograms of manure or sheep manure should be applied to the plants as the base fertilizer, which will help the new buds grow sturdily and sprout neatly in the next spring.
Management method of adult trees: the fruit trees enter the fruiting period in the fourth year, and only with sufficient fertilizer and water can the harvest and high yield be guaranteed. Fruit-picking fertilizer (winter fertilizer): 7- 10 days after harvest, organic fertilizer is the main fertilizer, with a small amount of urea and a proper amount of calcium magnesium phosphate fertilizer. Fertilizer in winter accounts for 40-60% of the total amount of fertilizer applied in the whole year.
Pre-germination fertilizer (spring fertilizer): used before the germination stage of spring shoots 10- 15 days, mainly based on quick-acting base fertilizer, with appropriate amount of phosphorus and potassium fertilizer. The application amount of spring fertilizer accounts for 15-25% of the total annual application amount. Fruit-strengthening fertilizer (autumn shoot fertilizer): It is applied before the autumn shoot germinates 10- 15 days, and the application amount is 20-40% of the total fertilization amount in the whole year.
The tree shape of shaping and pruning high-quality harvest garden is: the tree body is thick, the branches are luxuriant, and the leaves are green and thick; The trunk is convex and concave, small at the top and large at the bottom; The stem is short, the branches are happy, the branches are numerous, dense and symmetrical; The internal structure of the trunk has dense and symmetrical branches, slightly sparse outside, a large number of leaves and a reasonable number of fruit branches, showing a tree shape with three-dimensional conclusions.
