Problems solved by technology

[0004] ⑵Low yield: Once the tree vigor grows too vigorously, the formed flowers and fruits are easy to fall off, resulting in low yield;
[0005] (3) Insufficient nutrient control after girdling: after girdling, general winter jujube trees can achieve the purpose of controlling vigorous growth, but for more fertile planting areas, the effect is not obvious;
[0006] ⑷The economic benefits are low: the current average yield of winter jujube per mu is about 500-800 kg, the economic benefits are low, and the enthusiasm of farmers is generally not high

Embodiment 1

[0018] according to figure 1 Shown, a kind of winter jujube tree nutritional control root-cutting high-yielding method, its steps are as follows:

[0019] ⑴ Control humidity and timing: After entering May, pay attention to and grasp the moisture content of the jujube orchard. In case of drought, fill half of the ditch with water a week in advance, and proceed in time after the water dries up; in case of continuous rainy weather, find the right time to cut, and do not delay cutting time;

[0020] ⑵Cutting and girdling: the cutting time is May 15, based on the beginning of flowering of jujube trees, the length of the jujube hanging is 10-15cm; along the longitudinal direction of the tree row, on both sides of the 90cm distance from the main trunk, the tool is inclined at 30° and cut 40cm That is, cut off the root system, and cover the gap after cutting the root with soil to prevent rainwater from penetrating the rotten root, and it is also convenient for the root to grow in the...

Embodiment 2

[0024] according to figure 1 Shown, a kind of winter jujube tree nutritional control root-cutting high-yielding method, its steps are as follows:

[0025] ⑴ Control humidity and timing: After entering May, pay attention to and grasp the moisture content of the jujube orchard. In case of drought, fill half of the ditch with water a week in advance, and proceed in time after the water dries up; in case of continuous rainy weather, find the right time to cut, and do not delay cutting time;

[0026] ⑵Cutting and girdling: The cutting time is May 20, based on the beginning flowering stage of the jujube tree, the length of the jujube hanging is 10-15cm; along the longitudinal direction of the tree row, on both sides of the 120cm away from the main trunk, the tool is inclined at 30° and cut 50cm That is, cut off the root system, and cover the gap after cutting the root with soil to prevent rainwater from penetrating the rotten root, and it is also convenient for the root to grow in ...

Embodiment 3

[0030] according to figure 1 Shown, a kind of winter jujube tree nutritional control root-cutting high-yielding method, its steps are as follows:

[0031] ⑴ Control humidity and timing: After entering May, pay attention to and grasp the moisture content of the jujube orchard. In case of drought, fill half of the ditch with water a week in advance, and proceed in time after the water dries up; in case of continuous rainy weather, find the right time to cut, and do not delay cutting time;

[0032] (2) Cutting and girdling: The cutting time is May 18, based on the beginning of flowering of jujube trees, the length of the jujube hanging is 10-15cm; along the longitudinal direction of the tree row, on both sides of the 70cm away from the main trunk, the tool is inclined at 30° and cut 45cm That is, cut off the root system, and cover the gap after cutting the root with soil to prevent rainwater from penetrating the rotten root, and it is also convenient for the root to grow in the ...

Abstract

The invention relates to a root cutting and high-yield method for nutrition control of a winter jujube tree, which comprises the following steps of: (1) controlling the humidity and time; (2) cutting and girdling; (3) controlling the humidity and fertilizer application; and (4) bud picking. The method has the advantages that the excessive growth of the tree is controlled, the operation is simple, and the method is convenient to popularize and apply in the rural areas; the yield is increased by about 30%, the acre yield is increased by about 500 kg according to 110 plants per mu, and the net benefit of yield per mu is increased by over 2000 yuan; and the economic benefit is improved, the industrial scale is broad, the initiative of farmers is improved, and powerful guarantee is provided for eliminating barren for afforestation.

Description

technical field [0001] The invention relates to the technical field of agriculture and forestry planting, in particular to a method for nutrition control and root cutting of winter jujube trees to increase yield. Background technique [0002] With the implementation of the national policy of returning farmland to forests, since 2000, many counties and cities across the country, especially the southern region (taking Xiaochang County, Hubei Province as an example), have introduced winter jujubes that have been planted in the northern region for many years, and planted them at a rate of 2,000 mu per year. This not only reduces barren slopes and hillocks, but also increases the income of the masses. But there are following technical problems in the planting process of winter jujube: [0003] (1) Excessive growth of tree vigor: The climate in the former northern region is dry, but Xiaochang County is located in the Yangtze River Basin, with abundant rainfall and high soil humid...
