为解决上海丰黄桃低产,作者不仅对丰黄桃生长结果习性进行了观察,而且在授粉、整枝修剪、肥料、生长激素等方面进行了试验,并取得不同程度的效果。大面积生产采用了缓和树势、改善光照、抑制生长的栽培技术。1983年在长期阴雨的气候条件下,丰黄桃产量接近同龄的白凤桃水平。1984年经重复试验结果,总产量比1983年增加2.4倍.作者初步认为上海丰黄桃低产的主要原因是:(1)授粉不良,受精结实率低,达不到应有的结果量。(2)生长旺盛,生殖生长和营养生长平衡失调,生理落果严重.从而围绕改善授粉条件,提高受精结实率和调节树势等方面,提出了丰黄桃丰产栽培的技术意见。
In order to solve the low yield of Shanghai Feng Huang Peach, the author not only observed the growth habit of Feng Huang peach, but also experimented on pollination, pruning, fertilizers and growth hormone, and obtained different degrees of effects. Large-scale production has used to ease the tree vigor, improve the light, inhibit the growth of cultivation techniques. In 1983 in the long-term overcast and rainy weather conditions, Feng Huang peach yield close to the same age Baifeng peach level. The results of the repeated tests in 1984 showed that the total output increased by 2.4 times compared with that in 1983. The authors mainly consider the main reasons for the low yield of Shanghai peach peach are: (1) poor pollination, low fertilization and seed setting rate, failing to meet the required results. (2) Strong growth, imbalance of reproductive growth and vegetative growth, severe physiological declension, and technical advice on high yielding cultivation of Fenghuo peach was put forward in the aspects of improving pollination conditions, improving seed setting rate and adjusting tree vigor.
