Embodiment 1

[0017] A kind of cultivation method of green ecological jujube, comprises the following steps:

[0018] (1) Nursery stock breeding: choose jujube tree as rootstock, choose the first branch or secondary branch of 1-3 year old jujube as scion, and carry out grafting, and the grafting thickness is 2-5cm;

[0019] (2) planting: select healthy grafted seedlings without damage by diseases and insect pests to plant and build gardens in the spring, plant and complete irrigation in time, topping at the height of seedlings at 80-90cm, jujube planting density is: column spacing 2-3m, row spacing 3-5m, Plant peanuts within 1-2 years after planting;

[0020] (3) Fertilizer and water management: Top-dress the soil twice a year before germination and in late June. In the first year, apply 30g of urea, 100g of superphosphate, and 300g of farmyard manure to each plant. From the second to fourth years, apply 32kg of organic fertilizer to each plant. Urea 0.13kg, calcium superphosphate 0.4kg, f...

Abstract

The invention discloses a green ecological jujube tree cultivation method. The green ecological jujube tree cultivation method includes the following steps that a wild jujube tree is selected as a stock, a 1-3-year-old jujube head primary shoot or secondary shoot is selected as a scion, and grafting is conducted; a healthy and plant-disease-and-pest-free grafted seedling is selected to be transplanted in spring for orchard establishment, after transplanting is completed, irrigation is conducted in time, and peanuts or sweet potatoes are interplanted 1-2 years after field planting; soil dressing is conducted twice before sprouting every year and in the last ten days of June; pruning is conducted, wherein a multi-main-branch open-center shape is adopted, a trunk is 1 m high, 4 main branches are reserved, and 3-4 lateral branches are arranged for each main branch; prevention and control of Contarinia datifolia Jiang, cnidocampa flavescens and red spider plant diseases and pests are conducted; processing candied jujubes are harvested in the white ripe season, and the fresh eating jujubes are harvested in the crispy ripe season; the peanuts or the sweet potatoes are interplanted under the jujube tree, resources are fully utilized, and income is increased; by means of farmyard manure, formation of a soil granular structure can be promoted, the ratio of air to water in soil is coordinated, the soil is loose, and the capacity of water retention, temperature retention, air permeability and fertilizer retaining is improved.

Description

technical field [0001] The invention belongs to the field of agricultural technology, in particular to a method for cultivating green ecological jujube trees. Background technique [0002] Jujube trees are native to my country and have been planted for more than 3,000 years. It is widely distributed in our country, and its dried and fresh fruits can be used as food or medicine, rich in nutrients and high in economic value. Jujube trees are easy to reproduce, strong in resistance, early in fruiting and high in economic value. According to the survey, every 100g of pulp contains 380-600mg of vitamin C, which is 10 times higher than that of citrus and 80 times higher than that of apple. Fresh dates contain 25%-35% sugar. Jujube can be used as medicine, and jujube meat contains rutin, which has a significant medicinal effect on high blood pressure. [0003] Jujube forest has the functions of windproof, sand-fixing, reducing wind speed, regulating temperature, preventing and ...
