1.在绥中地区红元帅落花高峰是在5月15日前后,影响落花的主要因素是授粉和受精不良。红元帅生理落果有两个高峰,第一个高峰是在5月末到6月初,引起这次生理落果的主要原因,是新梢旺盛生长与座果的矛盾;第二次生理落果是与果实膨大和花芽分化有关。在加强肥水的基础上,控制新梢旺盛生长,是提高座果率的有效措施。 2.对生长强旺的辅养枝,于初花期环剥,不仅有利于座果,而且有利于花芽形成。 3.在第一次生理落果前15天,对果台付梢摘心,削弱其生长势,有利于座果。 4.在花序分离初期疏边花,使营养物质集中,能提高座果率。 5.微量元素硼和铜能活化苹果树的新陈代谢,加强营养物质的合成与利用,有利于受精作用,可以提高座果率。 6.盛花初期叶面喷1000倍醋酸液,座果率可提高20％左右。
1. In the Suizhong region Red Marshal peak of the flower falls around May 15, the main factors affecting the fall is pollination and fertilization poor. Physiognomy of Red Marshal has two peaks, the first peak is in late May to early June, the main reason for the physical drop caused by the strong growth of new shoots and the contradiction between fruit; the second physiological drop fruit and the fruit is swollen And flower bud differentiation. On the basis of strengthening fertilizer and water, controlling the vigorous growth of new shoots is an effective measure to increase the fruit set rate. 2. On the growth of the strong supporting branch, at the beginning of florescence, not only conducive to the fruit, but also conducive to the formation of flower buds. 3. In the first 15 days before the physiological decadent, pay off on the fruit topping, weakening its growth potential, is conducive to the fruit. 4 in the initial inflorescence sparse lace flower, so that nutrients are concentrated, can improve fruit set rate. 5. Trace elements boron and copper can activate apple tree metabolism, enhance the synthesis and utilization of nutrients, is conducive to fertilization, can improve the rate of fruit set. 6. Full bloom early foliar spray 1000 times the liquid acetic acid, fruit rate can be increased by about 20%.
