Embodiment 1

[0038] Take the vegetables cultivated in the Gobi Desert in Akto County, Kezhou, Xinjiang as an example:

[0039] Cultivation structure such as figure 1 As shown, it includes a cultivation base layer 1, an 8 μm thick polyethylene film water-retaining layer 2 and a cultivation ridge 3 from bottom to top. Between the cultivation ridges 3 are naturally formed furrows 4; The gravel layer 5 and the fine sand soil layer 6 of the upper layer; a small irrigation ditch 7 is left in the center of the cultivation ridge 3 top; exposed.

[0040] Among them, the height of the cultivated ridge is about 45 cm, the width of the bottom of the ridge is about 70 cm, and the distance between the ridges is about 50 cm; the plastic film water retention layer is concave; two rows of vegetables are cultivated in each ridge.

[0041] The cultivation method is as follows:

[0042] 1) Level the ground, loosen the depth of about 30 cm, and use a sieve with an aperture of about 15 mm to sieve the loosen...

Embodiment 2

[0047] Take the cultivation of vegetables in coastal saline-alkali land in Shouguang City, Shandong Province as an example:

[0048] The height of the cultivated ridge is about 45 cm, the width of the bottom of the ridge is about 70 cm, and the distance between the ridges is about 50 cm; the water-retaining layer of plastic film is horizontal; two rows of vegetables are cultivated in each ridge.

[0049] The cultivation method is as follows:

[0050] 1) Loosen the soil, the direction of loosening is perpendicular to the direction of the cultivation ridge, the depth of loosening is about 20 cm, and the soil is moved to the ground more than 70 cm in front while loosening. After loosening and turning more than 70 centimeters (this is the position where the cultivation ridge is located, it is the width of the bottom of the cultivation ridge), the turned over ground is smooth and smooth, and covered with a plastic film with a width of 70 centimeters. Continue to loosen and turn 12...

Embodiment 3

[0055] Take the vegetables cultivated in the semi-arid area of ​​Kangping County, Liaoning as an example:

[0056] Among them, the height of the cultivated ridge is about 45 cm, the width of the bottom of the ridge is about 70 cm, and the distance between the ridges is about 50 cm; the plastic film water retention layer is concave; two rows of vegetables are cultivated in each ridge.

[0057] The cultivation method is as follows:

[0058] The process of loosening the soil, laying the water-retaining layer, and building up the cultivation ridge is similar to "Example 2", but the difference is that when the plastic film is laid, the ground is processed into a concave arc surface, so that the bottom of the cultivation ridge looks like a shallow ditch.

[0059] Two rows of vegetables are cultivated on each ridge, and the cultivation period is 9 months. Varieties: tomato, strawberry.

[0060] Through the cultivation method of the present invention, the yield per mu is 5,831 kilog...

Abstract

The invention provides a water-saving cultivating method, which comprises the following steps of: (1) pretreating a land, and paving water holding layers at intervals on the treated land, wherein an interval width is 0.1-3.5 times of the width of each water holding layer; (2) building cultivating ridges on the water holding layers paved in the step (1) with soil among the water holding layers or transported soil, wherein an earth furrow is naturally formed between two cultivating ridges, and a water holding layer of 0.1-5 centimeters on each edge of the bottom of each cultivating ridge is uncovered; and (3) conventionally spraying the cultivating ridges built in the step (2), making moisture carry saline and alkaline substances from the cultivating ridges into the earth furrow, and cultivating plants on the cultivating ridges with a conventional method till the pH value reaches 6-8. The method is suitable for deserts, gobi deserts and salt licks, is simple and practical, and contributes to saving water resources.

Description

technical field [0001] The invention relates to an agricultural cultivation method, in particular to a water-saving cultivation method capable of carrying out agricultural production in non-cultivated lands such as the Gobi Desert and saline-alkali land, and a cultivation structure established by the method. Background technique [0002] Arid deserts, Gobi deserts and other harsh land areas that are not conducive to plant growth account for about 20% of my country's land area. Under such harsh environmental conditions such as drought, little rain, barren land, large temperature difference between day and night, and strong sunshine, few plants grow. , the ecological environment is fragile. [0003] There are about 380 million ha of saline-alkali land in the world 2 , our country has about 100 million hm 2 . And there are about 67 million hm of existing cultivated land 2 of the land belongs to the salinized low-yield field, and there are 33.33 million hm in my country 2 sa...
