Tomato pruning new method
First, in order to increase the leaf area, improve the photosynthesis of tomato, promote the growth of seedlings, and shorten the period of seedling sowing, the first inflorescence below the lateral vine (fork head) should not be cut off prematurely. Should be cut off after seeing the first flower bud. This is done to increase the growth of tomato in the early stage and promote early fruiting.
2. When the first inflorescence or side vines (fork heads) are cut, the bottom leaves should be retained, only the fork heads should be removed, and more than two leaves should be added to increase the photosynthetic capacity of leaves and promote fruit weight gain.
Third, the bundled tomato vines should take a type of bending rise. That is to say, the first inflorescence is tied to the base and restrains the nutrients to quickly transport the second inflorescence to the top and then binds in the opposite direction. Or tie the rope in front of the inflorescence, can be tight (ie twisted), tied and continuous, its role is to prevent nutrients quickly up the transport, the nutrients concentrated in the fruit, to 0.2 meters when released.
Fourth, the average tomato has 7 to 9 or 4 to 5 fruit. After many years of experimentation, 3 to 4 fruit per inflorescence are preferred. Its retention method: Headgear retains three, two or three fruit stays four, four or five stays three to four. To 3 to 4 is good, thin flowers should be removed before the flowering weak inflorescence. This stay, large, high yield, also reduces the appearance of malformed fruit. There is a saying of vegetable growers that "there is not so high yield."
V. There are two types of tomato varieties, self-sealing and infinity growth. Infinity growth type to leave a few fruit fit? In determining the fruit set criteria, of course, we must first consider fertility, fertility, growth potential and so on. Under normal circumstances, the north of the Great Wall stays 3 to 4 aircrafts, and the south of the Great Wall remains 4 to 5 aircrafts. It is better not to stay. Especially in multiple cropping areas, attention should be paid to the number of fruiting trips, and the multiple cropping index and economic benefits should be improved.
Sixth, the use of the above-mentioned method of pruning fruit should be combined with spraying plant growth regulators to promote tomato growth. According to the experiment, with the seedling stage and the stubble, use ABT to increase the yield of Ling No. 10 10 ~ 15PPm dip root or root. During the growth period, 500ppm “Anon†was sprayed and sprayed with Dydropenamine to control the growth. Spray 2 to 3 times per period as well, each interval of 7 to 10 days. The above hormones generally increase production by 15 to 20%, and the leaves are green, fruity, resistant to disease, and resistant to decay.
