1.根据我們两年丰产栽培試驗,在肥水充足管理周密并利用副梢結果的条件下,葡萄是可以連年获得高产的。今后应更深入地掌握葡萄各个物候期的生长发育规律,研究如何节約物力,巧施肥水,而仍达到丰产的目的,以便推广到实际生产中去。 2.我們认为,除紫玫瑰香已經普遍栽培外,我省可以推广丰产而多次結果的花叶白鸡心和金后两个品种。前者是早熟丰产品种,后者是晚熟丰产品种,这样可以延长葡萄的供应时期。 3.可以确定对金后、紫玫瑰香及黑罕三个品种利用逼冬芽以促使冬芽副梢結果的这个措施,在生产上是值得采用的。前两个品种可以增产20％,后者为10％左右。 4.关于逼冬芽时期問題上,金后、紫玫瑰香、黑罕、白玫瑰香和白香水五个品种,一致以主梢摘心后30天逼冬芽为最好,其时期是在开花后两周左右,在郑州地区是在五月底六月初。至于20天逼冬芽的,虽然它的二次果的平均重与30天的相同或有时反而較重,但是它的单位枝上的平均穗数較少,从而其每株二次果的总产量远不如30天的为高,因此,过早逼冬芽殊不适宜。40天和50天逼冬芽的,其二次果开花时期为7,月中旬前后,适值雨季,常会遇兩而减少其座果率,而且果实发育和成熟較晚,产量不高。 5.早期逼冬芽可以促进一次果的发育而增高其产量,其作用与摘心同。 6.葡萄五个品种中,以金后、紫玫瑰香逼冬芽結果最易成功,白玫瑰次之,而以黑罕和白香水为最差。 7.关于利用冬芽副梢結果和夏芽副梢結果孰为有利的問題,六个品种中,除花叶白鸡心外,其余五个品种都以冬芽副梢結果为宜,而且較有把握。白香水夏芽副梢不結果,只有利用冬芽副梢以获二次果,紫玫瑰香和白玫瑰香在良好栽培条件下,利用当年副梢結果,也可得到相当良好成績。所有品种若利用冬、夏芽两种副梢同时結果的方法,并不能得到預期效果。花叶白鸡心两年來都以夏芽副梢結果为佳。 8.葡萄的四次果穗頗小,其平均重量,金后为40—50克,紫玫瑰香为25—30克,而且仅占全株总产量的百分之一、二。两年来丰产地上均如此,因此,殊无利用价值。
1. According to our two years of high yielding cultivation test, adequate fertilizer and water management and the use of secondary shoot the results of the conditions, grapes can be obtained in successive years of high yield. In the future, we should further understand the law of growth and development of various grape phenophases and study how to conserve material resources and fertilize water, while still achieving the purpose of high yield, in order to promote it to practical production. 2. In our opinion, in addition to purple rose incense has been generally cultivated, the province can promote high yield and repeated results of the Mochi heart and golden two varieties. The former is a precocious variety, the latter is a late mature variety, which can extend the supply of grapes. 3. It can be determined that after gold, purple rose incense and black han three varieties of forced winter buds to promote the results of the winter bud secondary shoot this measure is in production is worth using. The first two varieties can increase 20%, the latter is about 10%. 4. On the issue of forced winter buds, golden, purple rose incense, black rare, white rose incense and white perfume five varieties, consistent with the main tip of the pinching 30 days aftercing winter bud is best, its period is after flowering two Around the week, the Zhengzhou area is at the end of May and early June. As for the 20-day forced winter bud, although its secondary fruit average weight and 30 days of the same or sometimes heavier, but its average number of spikes per unit branch less, so that each of its secondary fruiting production Far less than 30 days for the high, therefore, premature winter bud is inappropriate. 40 days and 50 days forcing winter buds, the second fruit flowering period of 7, around mid-month, the value of the rainy season, often encounter two and reduce the rate of fruit set, and the fruit development and maturation late, the yield is not high. 5. Early forced winter buds can promote the development of a fruit and increase their yield, its role and with the same. 6. Grape five varieties, after the gold, purple rose incense forced winter buds the most successful, followed by white rose, while black and white perfume for the worst. 7 on the use of winter shoots and the results of the shoots and summer shoots which shoot the results of which is favorable for the benefit of the six varieties, in addition to Mauca white heart, the remaining five varieties of winter shoots are the appropriate results, and more sure. Perfume Summer Bud Vice shoot is not the result, only the use of winter shoots secondary shoots to obtain secondary fruit, purple rose and white rose incense in good cultivation conditions, the use of the results of the shunt that year can also be quite good results. All varieties if the use of winter and summer buds two kinds of tips at the same time the results of the method and can not get the desired results. Mosaic white chicken heart summer buds are the best results. 8. Grapes four ear is quite small, the average weight of 40-50 grams of gold, purple rose incense 25-30 grams, and only the total plant output of one percent, two. In the past two years, all the high yield areas are so, therefore, no special value.
