In recent years, the continuous occurrence of Apple frost damage during the flowering period has brought a lot of economic losses to production. In particular, the orchards that take flowers and fruits have suffered more disaster losses, and there have been local harvests. In view of this situation, we have observed and experimented for 2 years (years) and summarized the three-step method of sparse flowering and sparse fruiting (ie early sparse inflorescence, timely sparse fruiting, and appropriate late fruiting) to avoid or reduce flowering frosts. Effect on fruit setting. The introduction is as follows. 1 The early sparse inflorescence advances the initial sparse flowering at the time of inflorescence separation to the time of inflorescence elongation. In accordance with the overall requirements of thinning and fruit thinning, complete inflorescences should be left in the positions where fruit must be left, and it is not necessary to completely eliminate the fruit inflorescences. In this way, the sparse flowers can be prevented from causing close wounds to the retained flowers, thereby preventing the cryogenic damage to the wounds, extending the affected flowers or young fruits, and substantially avoiding or alleviating the night cream. The hazards. 2 timely sparse fruit when the fruit set is stable, the weather will no longer appear more severe cold air (cold stream) when the fruit is to be thinned. It is generally believed that the fruit thinning insurance period in Sanmenxia area should be determined at the end of April and beginning of May. Premature weather is not stable, but there are still cold attacks; when too late, excessive young fruit consumes nutrients and produces a large number of flowering hormones, which will inhibit the flower bud differentiation that follows, and affect the early growth and development of fruits that should be preserved. Generally sparse fruit should be finished in the middle of May (this considers that there is a suitable period of fruit bagging factors), so that each inflorescence leaves a single fruit. 3 During the process of fruit thinning and fruit thinning, the late fruiting period of appropriate period should leave about 10% of the fruit and fruit for insurance. During the growth and development of young fruit, there will be some fruits that are damaged by climate, pests, birds, and production operations, resulting in deformed fruit, wounded fruit or small fruit, in order to reduce the number of trees left in the unqualified fruit, guaranteeing The ratio of high-quality fruit in the year must be appropriately delayed. For example, in Japan, fruit is determined when young fruit is larger than table tennis.
