Problems solved by technology

When constructing farmland shelterbelts during production, poplars are usually selected as the main tree species for afforestation. Poplars are less resistant to salt and alkali than Jujube, and they are divided into main forest belts (perpendicular to the main wind direction) and auxiliary forest belts (parallel to the main wind direction). 4-6 rows of trees are planted in the forest belt, and 2-3 rows of trees are planted in the sub-forest belt, and they are all planted around the farmland, occupying a large area of ​​farmland, and have a great adverse effect on the production reduction caused by shading of farmland crops
At the same time, because poplar has the characteristics of fast growth and straight stem, the construction of farmland shelterbelts can play a fast role in ecological protection, but the effect of biological nitrogen fixation and saline-alkali soil improvement is not obvious, and it is impossible to realize economic benefits every year.

Embodiment 1

[0027] (1) Deep plow the saline-alkali soil, dry it until it can be mechanically rolled, divide it into 100m long and 20m wide fields, excavate 80m wide water canals around the fields, and use them as canal ridges to synchronize with cotton field sowing. The row spacing of cotton in the described cotton field is 60cm, and the plant spacing of cotton is 8cm, and the sowing depth of cotton is 3cm, selects the biennial cuttage seedlings of the strong uprightness of the canopy, and in spring, along the ditches on both sides of the canal, according to the 3m The distance between the plants is carried out to plant 2 rows of saplings of Jujube saplings in a character shape;

[0028] (2) Irrigate cotton fields;

[0029] (3) After the cutting seedlings survived, wipe the buds and trim the side branches in time, so as to promote the high growth of the big scorpion, cultivate the main trunk, and control the height of the branches to 1.5m.

[0030] During this period, there is no need to...

Embodiment 2

[0032] (1) Deep plow the saline-alkali land soil, dry it until it can be mechanically rolled, divide it into 100m long and 20m wide field pieces, excavate 80cm wide water channels around the field pieces, make canal ridges, and synchronize with cotton field sowing. The row spacing of cotton in the field is 70cm, the plant spacing of cotton is 10cm, and the sowing depth of cotton is 4cm. Select the biennial cutting seedlings of the big upright tree canopy. Carry out the character type planting 2 rows of big sandy jujube trees;

[0033] (2) Irrigate cotton fields;

[0034] (3) After the cutting seedlings survive, timely take measures to smear buds and trim side branches, cultivate the main trunk, and control the height of the branches to 1.5m.

[0035] During this period, there is no need to take any management measures such as fertilization and weeding. After 3 years of planting, a small amount of fruiting began to appear. At the same time, the benefits of ecological protectio...

Embodiment 3

[0037] (1) Excavate the saline-alkali land and dry it until it can be mechanically rolled. After rolling and leveling, excavate the blind ditch for salt drainage, backfill the medical stone and the blind pipe, and after the pretreatment is completed, it will be synchronized with the sowing of the cotton field. The row spacing of cotton is 60cm, the plant spacing of cotton is 8cm, and the sowing depth of cotton is 3cm. Plant 2 rows of large jujube trees with a plant spacing of 3m;

[0038] (2) Irrigate cotton fields;

[0039] (3) After the cutting seedlings survive, timely take measures to smear buds and trim side branches, cultivate the main trunk, and control the height of the branches to 1.6m.

[0040] During this period, no management measures such as fertilization and weeding were required. After 3 years of planting, a small amount of fruiting began to appear. At the same time, the benefits of ecological protection also appeared in time. It entered the early stage of fruiti...

Abstract

The invention discloses a method for establishing cotton field protection forest in newly-cultivated saline-alkali land. According to the method, cotton is planted in the saline-alkali land, a cotton field is formed, and the elaeagnus moorcroftii protection forest is built on channel ridges on the two sides of channels around the cotton field in a delta-shaped planting mode; and by utilizing the situation that elaeagnus moorcroftii nodule bacteria has the characteristic of biological nitrogen fixation, in the growth process, even if fertilization is not conducted, elaeagnus moorcroftii trees can also normally grow, bloom and bear fruits, the tree body tending management process is simplified, the productivity level of the saline-alkali land is improved, and the management cost is saved.

Description

technical field [0001] The invention relates to the technical field of planting shelterbelts on saline-alkali lands, in particular to a method for establishing cotton-field shelterbelts in newly reclaimed saline-alkali lands. Background technique [0002] As global temperatures rise, rainfall decreases year by year, and droughts are getting worse. There are many desert areas in Xinjiang, and the rainfall is relatively low. The surrounding lakes are gradually drying up. In addition, due to the impact of desertification, the lakes gradually become saline-alkali land after drying up, and it is difficult to recover. Xinjiang is located in the northwest of my country. Because it belongs to a typical inland arid climate, agricultural production is almost entirely dependent on artificial irrigation. One of the consequences is that these salts continue to enter the cultivated land. Under the condition of inland dry and early climate, the soil leaching is very weak, and the water ri...
