Embodiment 1

[0026] Embodiment 1 (contrast)

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

[0028] Cucumber seedlings began to grow on March 1;

[0029] On March 20, foreign objects such as stones, straw, root stubble, etc. in the sand in the cultivation bed were picked out, and the sand in the cultivation bed was leveled;

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

[0031] On March 26, use a rotary tiller to till it twice, and fully mix organic fertilizer, base fertilizer and surface sand into nutrient soil 2;

[0032] On March 27, the position of the ridge was drawn according to the ridge distance of 1.2m, and then part of the nutrient soil 2 of the ridge 5 was turned over on the ridge 3 to form a ridge, forming a ridge height of...

Embodiment 2

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

[0036] Cucumber seedlings began to grow on March 1;

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

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

[0039] On March 26, use a rotary tiller to till it twice, and fully mix the pastoral soil, organic fertilizer and surface sand into nutrient soil 2;

[0040] On March 27, the position of ridge 3 w...

Embodiment 3

[0046] It is treated by the land preparation method of the guest soil method (E21 shed), and the specific operation is carried out according to the following steps:

[0047] Cucumber seedlings began to grow on March 1;

[0048] On March 20, the 16cm sand on the surface of the cultivation bed was transported out of the greenhouse, and foreign objects such as stones, straws, root stubbles, etc. in the sand in the cultivation bed were picked out, and the sand on the cultivation bed was leveled;

[0049] 60m transported from nearby farmland on March 25 3 Pastoral soil, spread evenly on the sand surface, forming a pastoral soil layer on the pure sand 1, the thickness of the soil layer is about 16cm, and then sprinkle 4m of decomposed chicken manure on the pastoral soil 3 ;

[0050] On March 26, use a rotary tiller to till it twice, and fully mix the pastoral soil, surface sand, organic fertilizer and base fertilizer into nutrient soil 2;

[0051] On March 27, the position of ridge...

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 substrate greenhouse by means of bed preparation technology. Background technique [0002] In recent years, due to the need to vigorously develop facility agriculture without occupying the original cultivated land, southern Xinjiang has begun to build large-scale greenhouses in desert areas. In Hotan area alone, 100,000 mu of greenhouses have been planned, and some of them have been put into production. Due to the shortage of arable land resources, the greenhouses are built on the flattened sand dunes 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, so the greenhouse vegetables caused by the pure sand cultivation medium Growth and nutritional disorders are very common. Specifically, the ma...
