柑桔一般座果率很低,通常只有2—3%。设法提高其座果率,是增产的重要环节。产生柑桔大量落花落果的基本原因在于植物体内营养状况不够协调,因此及时设法调节、补充其营养,可以提高着果率。根外追肥在这一方面大有应用前途,另外某些生长刺激素在一定浓度内能够抑制离层产生,也有防止落花落果的效果。因此我们今年在城(?)升仙村进行了有关试验,目的在于查明在当地一般管理水平下防止落花落果的有效措施,以期提高当地柑桔产量。
Citrus fruit rate is generally low, usually only 2-3%. Trying to increase their fruit set rate is an important part of increasing production. The basic reason for producing a large number of falling flowers and falling fruits of citrus lies in the fact that the nutritional status of the plants is not coordinated enough so that timely adjustment and supplementation of nutrients can increase the fruit yield. Root top dressing in this area a lot of future applications, while some growth hormone in a certain concentration can inhibit the formation of layers, but also to prevent the effect of falling flowers. Therefore, we conducted a test this year in Sheung Sin Estate, City (?), Aiming at identifying effective measures to prevent the loss of fruit and vegetables at the local general management level so as to increase the output of local citrus fruits.
