Embodiment 1

[0026] Example 1 (control)

[0027] Control treatment (E17 shed): that is, the land preparation method routinely used in production. The specific operation is carried out according to the following steps:

[0028] On March 1, cucumbers began to grow seedlings;

[0029] On March 20th, foreign objects such as stones, straws, and stubble in the sandy soil of the cultivation bed were picked out, and the sandy soil of the cultivation bed was leveled;

[0030] On March 25th, evenly spread 4m of decomposed chicken manure on the pure sandy soil 1 3 , 17kg of diammonium phosphate, 7kg of urea and 10kg of potassium sulfate;

[0031] On March 26, the rotary tiller was used for 2 times of rotary tillage, and the organic fertilizer, base fertilizer and surface sand were fully mixed into nutrient soil 2;

[0032] On March 27, the position of the ridge was drawn according to the 1.2m ridge distance, and then part of the nutrient soil 2 of the ridge and furrow 5 was turned over on the ridg...

Embodiment 2

[0035] For the land preparation method processing (E19 shed) of the present invention, the concrete operation is carried out according to the following steps:

[0036] On March 1, cucumbers began to grow seedlings;

[0037] On March 20, the 8cm sandy soil on the surface of the cultivation bed was transported out of the greenhouse, and foreign objects such as stones, straws, and stubble in the sandy soil in the cultivation bed were picked out, and the sandy soil of the cultivation bed was leveled;

[0038] On March 25, 30m from the nearby farmland 3 The pastoral soil is evenly spread on the sand surface, and a pastoral soil layer is formed on the pure sandy soil 1, the thickness of the soil layer is about 8cm, and then 4m of decomposed chicken manure is spread on the pastoral soil. 3 ;

[0039] On March 26, the rotary tiller was used for 2 times of rotary tillage, and the pastoral soil, organic fertilizer and surface sand were fully mixed into nutritious soil 2;

[0040] On ...

Embodiment 3

[0046] For the land preparation method of the foreign soil method (E21 shed), the specific operation is carried out according to the following steps:

[0047] On March 1, cucumbers began to grow seedlings;

[0048] On March 20th, the 16cm sandy soil on the surface of the cultivation bed was transported out of the greenhouse, and foreign objects such as stones, straws, and stubble in the sandy soil in the cultivation bed were picked out, and the sandy soil of the cultivation bed was leveled;

[0049] On March 25, 60m from the nearby farmland 3 The pastoral soil was evenly spread on the sand surface, and a pastoral soil layer was formed on the pure sandy soil 1, the thickness of the soil layer was about 16cm, and then 4m of decomposed chicken manure was spread on the pastoral soil. 3 ;

[0050] On March 26, the rotary tiller was used for 2 times of rotary tillage, and the pastoral soil, surface sand, organic fertilizer and base fertilizer were fully mixed into nutrient soil 2; ...

Abstract

The invention relates to a soil preparation method for improving the production performance of soil in a sandy soil matrix greenhouse. According to the method, field soil is partially added in a pure sandy soil farming layer, the three-dimensional structure that sand is covered with soil, soil is coated with fertilizer and ridges are high is formed, and the pure sandy soil productivity is greatly improved. Based on the soil dressing principle, the good rooting performance, moisture and fertilizer retention performance, buffer performance, biological performance and nutrient performance of the field soil are kept, the pure sand layer is utilized for cutting off surface layer soil capillary force, the humidity in the greenhouse is lowered, and therefore diseases caused by high humidity in the greenhouse are greatly reduced. The soil temperature of the farming layer in winter is increased due to the fact that the ridges are high, and therefore the growth of vegetable root systems is promoted. Accordingly, the soil production performance and the vegetable output are greatly improved.

Description

technical field [0001] The invention relates to the field of crop cultivation, and relates to a soil preparation method for greatly improving the production performance of a sandy soil matrix greenhouse through a furrow preparation technology. Background technique [0002] In recent years, due to the need to vigorously develop facility agriculture without occupying the original arable land, southern Xinjiang has begun to build greenhouses on a large scale in desert areas. Only in Hotan area, 100,000 mu of greenhouses have been planned, and some of them have already been put into production. Due to the shortage of arable land resources, the greenhouse is built on the sand dunes that are flattened outside the oasis. The cultivation medium is fine sand with a soil content of less than 5%. Pure sand cannot provide the perfect function of normal soil. Therefore, greenhouse vegetables caused by pure sand cultivation medium Growth disorders are common. Specifically, the main obsta...
