First, "two stop" period of fertilization watering. In order to ease the overgrowth of branches and leaves, and to promote the growth of branches and leaves, the trees that grow energetically and have little or unproductive results should avoid the prolonged long-term, and after the new shoots are stopped, the spring shoots are stopped for a long time and the autumn shoots are stopped for a long time ( Late August and early September) Top dressing. Fertilizer application of long-acting fertilizer is better, such as human fecal urine or superphosphate, the general apple tree to nitrogen, phosphorus, potassium absorption ratio of 2:1:2, and young trees absorb more nitrogen. After top dressing, the amount of watering should be appropriate. When the shoot is stopped for a long time, the amount of watering after top dressing can be slightly larger. During the rainy season, the rainwater should be drained and flooded in time to control the shoots and greed. Second, foliar spray fertilizer. From apple young fruit trees to primary fruit trees, they sprayed 300 times potassium dihydrogen phosphate twice each in the middle and early September, which can promote the ripening of branches, increase the photosynthetic intensity of leaves, and promote the formation of flower buds. Third, open the angle. You can ease tree vigor and help flower bud differentiation. The methods mainly include pulling branches, branching branches, branches, outside buds, and replacing the back. Pulling time should be carried out at the beginning of tree growth and the end of growth (from late August to late September). Fourth, carved buds to promote flowers. For unsuccessful young apple trees, as long as the branches have not yet severely affected the light of the trees, they should be as sparsely cut as possible. Before the apple sprouts, the remaining branches can be singulated in multiple ways to promote flower bud differentiation and early results. . Fifth, twisting girdling. Twist tip is used for erecting prosperous new shoots on the back. When the new shoot grows to 20-30 cm, it is used to pinch the upper lignified part of the shoot and gently twist it 180 degrees. Due to the destruction of the transduction tissue, the backflow of the assimilation product of the shoot is hindered to control its prosperous growth and play a role in promoting flower bud formation. The girdling can temporarily hinder the nutrient delivery down the tree and increase the accumulation of nutrients above the girdling site. Sixth, deep rooting. For juvenile apple orchards, combined with autumn basal fertilizer, deep pruning of the soil for pruning roots can weaken root growth, adjust the contradiction of tree growth and fruit setting, improve the accumulation of nutrients in shoots, and make more nutrition available for flower bud differentiation. Seven, chemical promotion flower. Chemically promoting flowers is the use of plant growth regulators to control the conversion of vegetative growth to reproductive growth of juvenile trees to achieve the purpose of controlling crown and promoting flower growth. Paclobutrazol, which is commonly used in production, is a growth retardant with strong inhibitory activity. It has good effects in inhibiting growth and promoting flower bud formation. There are usually two methods, soil application and spraying.
