yongcheng jujube planting co. LTD
The winter jujube seedlings are strong, have strong cold resistance, high yield in years, and good fruit quality. It is a promising mid-maturing red jujube variety. It has the characteristics of fast-growing, long-term production, high yield and stability. The economic life span is more than 30 years, and the grafted seedlings are planted with 45-66 plants per mu. The results can be flowered in the same year. The planting can be harvested in 9 months, and the fresh dates will be listed from late October to March. The yield per mu is 500-700 kg. The second year is 800-1500 kg. In the fourth year, it can enter the high-yield period, with a yield of 4,500-6,000 kg per mu. In the planting of fruit trees, the second-generation winter jujube seedlings and jujubes are short-lived projects worth promoting. Areas below freezing in winter must be planted in greenhouses.
1. Winter jujube seedling foliar spray: After the fruit is harvested, spray 0.3-0.5% potassium dihydrogen phosphate as soon as possible to increase the nutrient accumulation of the tree, promote leaf assimilation and branching, and enhance the tree potential to facilitate wintering.
2, winter jujube seed application base fertilizer: the base fertilizer was applied at the beginning of October. In the initial fruiting period, each plant is applied with 20-30 kg of decomposed farmyard manure; in the fruiting period, 30-50 kg is applied per plant, and with 0.5-1.0 kg of urea, compound fertilizer (nitrogen: phosphorus: potassium = 15:12:15) ) 1.5 kg. It is applied by radial ditch application. It is the starting point at 1/2 of the tree plate, and the outer end is aligned with the outer edge of the canopy. Dig 7-9 radial grooves, 30-40 cm deep and 40 cm wide, will be mixed well. The fertilizer is scattered into the ditch and then covered with a layer of soil.
3, winter jujube seedling irrigation: the first water after the fruit is harvested, the amount of irrigation depends on the soil moisture, so that the soil moisture is most conducive to the growth and development of plum trees. When filling the water, the ditch is 20-25 cm deep between the Liyuan line. The ditch is preferably perpendicular to the water channel. After filling the water, fill the ditch in time.
