The Seedling technique of Yellow Fruit

Yellow fruit tree is a tree species with high economic value, its planting advantage is obvious, and its yield is high, the general yield per mu is 3000-4000 jin, and it takes only half a month from flowering to fruiting, and the labor cost is low. If you want to plant yellow fruit, raising seedlings is extremely important, so let's take a look at the seedling technology of yellow fruit with Xiaobian.

1. Rootstock cultivation

Take seeds from the large, nuclear and fully ripe yellow fruit, wash the pulp and cutin and dry them, and then sow them. The germination rate of fresh seeds is high, and seed drying will reduce the germination rate, so do not expose yourself to the sun. There are two ways of sowing, one is direct seeding, sowing seeds according to a certain row spacing, or sowing in a nutrition bowl, this seed benefit into seed soaking to accelerate germination yield, when the seed white or bud length less than 1 cm. There is also a kind of sowing, to now fertile, well-drained land, bed, leveling or in the nursery to build a sand bed, and then sow, the grain distance is 3 to 4 centimeters. After sowing, the loose fine sand is 1 cm, and the grass is covered with moisturizing, the seedlings are unearthed to remove high yield, strengthen fertilizer and water management and pest control, and transplant when the seedlings grow to 10-15 cm in the following spring.

2. Cultivation of grafted seedlings

When the diameter of the rootstock reaches 0.5 cm, it can be grafted. The grafting can be divided into spring and autumn. The grafting methods include leaning grafting, cutting grafting, split grafting and patch bud grafting. Eggplant depends on grafting in March-June every year, but the survival rate is the highest before and after Qingming Festival; cutting and splitting are in March-April, and scions are taken from the mature spring or autumn shoots growing on the upper and middle periphery of the crown on the excellent mother plant, and grafted on the rootstock 15-20 cm off the ground. Patch bud grafting is generally carried out in summer and autumn, where the trunk of the rootstock is about 30 cm from the ground, and the bud interface is generally larger than the bud piece, then cut the bud piece and stick it into the bud interface, then fasten it with the film, and untie the film in time when the incision heals.

3. Setting up a garden and planting

The planting land should be planted in areas with an average temperature of more than 20 ℃, and the soil should be loose and well drained and irrigated, preferably close to the source of water, and should not be planted on sticky, hardened and dry land. Planting is mainly from March to April or September to October, it is appropriate for seedlings to mature, and the planting density is determined by more management mode, soil and configuration characteristics. Generally, 66 plants are planted per mu, and holes are dug and base fertilizer is applied before planting. When planting, it is necessary to backfill topsoil, green manure, soil manure, livestock manure mixed with calcium fertilizer, magnesium fertilizer, phosphate fertilizer, each layer needs to be mixed with the soil, and finally the soil is 15 cm higher than the ground.
