Summer is a critical period for the development of Chinese chestnut fruits.
One, topping
Topping has the effect of increasing nutrient accumulation in the tree, changing the direction of movement of nutrients, inhibiting the influx of nutrients into the tip of the shoot, promoting the branching of fruit trees, enriching shoots, and controlling the crown. Dividing into the heart of grafted saplings, toppings, twigs and toppings, must be treated differently.
1. Grafting saplings and retractions. After mid-May, for the prosperous branches with space (including the grafted saplings and renewed large tree development branches), when the new shoots grow to more than 30 cm, the top 1 cm shoots are removed and new shoots are taken. When it grows to 25 centimeters or more, pick up the heart again. After that, as long as the branch is as long as 25 centimeters, it will be picked up.
2. Results Tips and male flowering branches topping. For the topping of the male squid, it should be confirmed that the twigs can no longer be used for female flowering and then topping; leaving 4-5 shoots to the top of the result. This period of topping can promote the concentration of nutrients, which can promote the increase of female flowers and the growth and development of young larvae, and extend the ability of the continuous branch of fruit trees.
3. Picking autumn shoots. The male squid, developing twigs, and fruiting twigs on Wang tree often germinate in the autumn. Since their growth period is short and the growth is not substantial, they should be completely removed.
Second, the male flower inflorescence
Chestnuts have a large number of male flowers, and the growth of male flowers consumes a lot of nutrients and moisture. When mixed (bisexual) inflorescences appear, the male inflorescences growing on the upper branch of the canopy remain two below the mixed inflorescence, leaving only one for the male inflorescences born on the resulting branches at the lower part of the canopy. For all the male inflorescences on simple male flowers, all were removed.
Three, Peng Peng
There are many varieties of chestnuts that are easy to grow into female flowers. Farmers generally think that such varieties have high yields and they rarely go to sparse, resulting in nutrient consumption. In the chestnut garden with good management level, sometimes a result can reach more than 10 canopy. If it is not suitable for the amount of evacuation, it will increase the rate of penthouse. Therefore, it should be carried out in early July. In general, the amount of fluff is generally: the strong result tree leaves 3-4 tents, the golden mean branch leaves 2-3 tents, the weak result branch leaves 1 tent, and the weak branches don't stay .
Fourth, bending branches
Curved branches are artificially changing the direction and angle of branches. Especially for dense planting gardens, it is an important method of pruning to rationally utilize space, advance results, and prevent baldness in the lower branches. Branches, branches, hanging branches, fallen branches, and litchi are all categories of curved branching measures. Time: In addition to lychee generally in mid-August to mid-September, other measures can generally be adopted in early spring and before sprouting and growing.
1. Pull the branches. When the length is more than 80 cm, it is necessary to pull it to the predetermined position in time. It is better not to be late as soon as possible, otherwise the base angle is difficult to open, causing chapped.
