1. Strengthen the tree's fertilizer management, increase the tree's nutrient reserve, in order to reduce the incomplete flower rate. Reasonable fertilization, especially the timely application of organic fertilizer after harvesting, can not only increase soil organic matter, improve soil effect, but also can supplement tree nutrient consumption. In the arid regions, water storage and fertilizer are used to supplement water and available fertilizers during the critical period of flower bud differentiation (if the expansion is substantial, hard core, and preharvest) to promote flower bud differentiation and reduce incomplete flower rates.
2. Reasonable pruning, timely adjustment of tree structure. In winter, when it is cut, it is necessary to control the weaker and weaker, and adjust the tree potential to the level of moderate dominance. Pruning of the resulting branches and combinations, appropriate short cuts to ensure a reasonable amount of flowers, can adjust the distribution of nutrients during fruit setting. Open the light path to allow the tree to be airy and transparent for the differentiation of flower buds. During the growing season, the leggy branches were dealt with promptly. The result branches and result branches of the internal branch were used for branching, pulling, and supporting, etc., and the branches were rationally placed.
3. Prevent and forecast and prevent frost from happening in time. In the flowering period and young fruit period, listen to the weather forecast at any time. When there is a cold current, preparations for smoke preparation can effectively prevent the occurrence of frost. At the same time, before flowering, the use of spray suppression transpiration agent, spraying salt water and trunk whitening method can delay the flowering period, avoiding the danger of late frost.
4. Flowering tree fertilization during flowering can increase fruit setting rate. Spraying 0.2%～0.3% urea and 0.2%～0.3% borax in the flowering tree all have the effect of increasing fruit setting rate.
5. Flowering bees during the flowering period increase pollination opportunities. Generally, every 1000 mu of apricot flat garden can be placed with 1000 bees.
6. Flowering pollen is sprayed during flowering to improve pollination.
