本试验在保定地区三个果园连续做了六年。用10％左右的蔗糖或食用糖溶液,在美夏(American Summer Pearmain)元帅(Delicious)苹果盛花初期喷施,可提高座果率5—8％。其效能是:诱来较多传粉蜂;增加柱头粘着力,喷糖液柱头上花粉粒较对照增加约三分之一,使花粉的萌发和花粉管的伸长表现出群体效应(Population effect)容易授粉和受精;提高花器的生理活性和抗逆性。1975年和1976年,在保定郊区、涞水、雄县观察美夏、元帅苹果花期遇不良天气,则雌蕊发育迟缓,柱头分泌物减少;雄蕊早衰、花粉早破死亡;传粉更有减少。座果率降低,产量下降。用涂白、喷硼、喷氮效果不太理想,为此参阅了 A·C 塔塔采夫教授用蔗糖液促使花粉萌发的试验和“养蜂学”中喂糖液可使蜜蜂复壮的材料,从77年至82年连续六年用蔗糖和食用糖液在美夏、元帅上进行了花期喷试,提高座果率5—8％,增产10—25％,用0.1斤糖溶在1斤水中可喷300—500花序,提高产量30—80斤,效果大增。
The experiment in Baoding three orchards for six consecutive years. Use about 10% sucrose or sugar solution in the early summer of the American Summer Pearmain Delicious apple blossom to increase fruitsetting by 5-8%. Its effectiveness is: luring more pollinating bees; increasing the stigma adhesion, the pollen grains on the head of the sugar-sprayed liquid increased by about one third compared with the control, which made the pollen germination and pollen tube elongation show the population effect. Easy to pollination and fertilization; improve flower physiological activity and resistance. In 1975 and 1976, in Baoding suburbs, Xishui and Xiongxian observed the summer of the United States, Marshal Apple flowering adverse weather, the pistil stunted growth, stigma secretion decreased; premature aging stool, pollen early rupture; pollination more reduced. Fruit rate decreased, the output decreased. The use of painted white, boron spray, nitrogen spray less than ideal, for reference, Professor A. C Tata Sev’s sucrose solution to promote pollen germination test and the “bee” in the sugar solution can make the bee rejuvenation material , From 77 to 82 for six consecutive years with sucrose and sugar solution in the United States Xia, Marshal on the spray test carried out to improve fruit set 5-8%, an increase of 10-25%, with 0.1 kg sugar dissolved in 1 kg The water can be sprayed 300-500 inflorescences, increase production 30-80 catties, the effect greatly increased.
