三、摘要1、关于葡萄主梢留叶多即摘心强度对副梢结果问题。金后品种生长势中等,分枝力强,以留入叶为好;白鸡心品种,生长势强,分枝力弱,以留三叶为好。2、不同时期逼冬芽,使冬芽副梢结果的问题。金后以主梢摘心后25天逼冬芽,促使冬芽副梢结果为最好,15天的次之。白鸡心也以25天的为好。金后冬芽副梢上的果穗,比一次副梢的果穗大得多,平均在175克以上,因此可以利用冬芽副梢结果的方法增加产量。白鸡心的各芽副梢的果穗不大,而其一次副梢上的果穗平均的重量(110克)不亚于冬芽副梢的果穗,而且由于它是早熟种,逼冬芽的适当时间甚为短促,所以在生产上是否逼冬芽的问题,还须作进一步的试验研究。3、关于以当年副梢结果为主或是以冬芽副梢结果为主的比较试验。金后葡萄则以逼冬芽,使冬芽副梢结果为好,并适当地配合一次副梢结果。白鸡心以当年副梢结果为好,可以适当地配合冬芽副梢结果。4、葡萄的四、五次果颇小,平均重量为40——50克,而且仅占全株总产量百分之一、二。所以今后应抓前几次的结果,以保证丰收。在提高第二、三次果产量的基础上,采取多种措施,提高四、五次果的质量,以争取更大的丰收。1960年我院幼令葡萄,尽管取得了较为高额的产量,初步摸索了一些丰产规律,但是由于师生们科学理论水平所限,实际经验不足,所以这些初步的成果,还须在今后生产中进一步去研究,去验证。其中难免有很多不妥之处,希望同志们多多提出指导批评。 Third, the abstract 1, on the main leaves of the leaves stay leaves that is more than the intensity of the sinuses on the results of secondary shoots. After the growth of gold varieties moderate, strong branching force to stay in the leaves as well; white chicken heart varieties, growing strong, weak branches to leave the clover as well. 2, force winter buds in different periods, so that the outcome of the winter bud Vice shooter problem. After the main shoot topping 25 days after gold forcing winter buds, prompting the outcome of winter buds for the best, 15 days second. White chicken heart also 25 days as well. The buds on the shoots of the late gold buds are much larger than those on the shoots of the secondary shoots, averaging over 175 grams, so the yield can be increased by using the results of the shoot shoots. White buds of each bud shoots ear is not big, and its secondary tips on the average weight of the ear (110 grams) as much as the ear of winter buds ear, and because it is precocious species, the appropriate time forcing winter buds Short, so whether to force winter buds in production, but also for further experimental study. 3, on the results of the main shrubs in the year or the main results of the comparison of winter shoots. Gold grape is to force winter buds, so that the outcome of winter buds as a good tip, and the appropriate time with a secondary tip results. White chicken heart that year as a result of secondary shoots, which can be properly matched with the results of winter shoots. 4, grape four or five fruit is quite small, the average weight of 40 - 50 grams, and only one percent of the total plant output, two. So in the future should be caught several times before the result, in order to ensure a good harvest. On the basis of increasing the output of the second and third fruit crops, various measures should be taken to raise the quality of the fourth and fifth fruit crops for greater harvest. In 1960, grapes in our institute grazed young grapes, although a relatively high yield was obtained and some laws of high yield were tentatively explored. However, due to the limited theoretical level of science and the limited practical experience of teachers and students, these preliminary achievements have to be produced in the future To further study, to verify. There are many unavoidable problems inevitably, and I hope that many comrades will give guidance and criticism.
