First, pulling branches, heavy short cuts
The result is that the site is moved outward, the base is bare, the growth is weak, and the results are small. The branches can be shrunk from the better branches, the new branches can be cultivated, and the healthy branches can be taken out, and the branches can also be used to make new branches. Function to achieve stereoscopic results.
Second, smear
Each result has 3 to 4 full buds in the upper part of the mother branch, and 1 to 2 in the lower part. The small buds are cut off, leaving large buds. For the dense ones, the inner ducks are cut off, leaving the outer buds, which is beneficial for concentration after erasing. Nutrients, promote plant growth, and are conducive to flowering and fruit setting.
Third, Shuxiong
The nutrient consumption of chestnut male flowers is large, so it is necessary to remove excess male flowers. The best effect is to remove the male inflorescences when the male inflorescence is 1~2cm long. After more than 10 days, the male and female mixed inflorescences can be grown, and the male flowers below are only kept 2~ Three male flowers are for pollination, and the rest are eliminated.
Fourth, fruit top picking
After the chestnut mixed flower buds grow out, the new shoots that continue to grow in front are the front tips of the fruit. At this time, leaving 3 to 4 leaves to pick the heart can greatly improve the fruit setting rate and reduce the emptiness.
Five, artificial pollination
Choose the varieties with large grain size, good quality, early maturity and high affinity for pollination trees. When the male inflorescences turn from green to yellow, pick the male flowers before 8:00 am, and put the picked male flowers on the glossy paper to dry, ventilate and The dusty place, flipping a few times a day, will pollen out after 24 hours, then you can collect pollen. When the female flower stigma begins to split, the method of brushing is used, and the first mature in the middle of a female stigma can be multi-pollinated several times.
Six, drip
Too much chestnut can not only be detrimental to the growth and development of the plant, but also cause the fruit to be years old. Therefore, when the diameter of the chestnut is 0.5cm, the excess canopy is removed and the nutrients are concentrated.
The standard of diarrhea is: young saplings are sparse, weaker branches are more sparse, peripheral and upper parts are less sparse, and inner sputum and lower part of the canopy are sparse.
