Problems solved by technology

However, in the field of facility production in my country at present, strawberry is mainly cultivated in matrix. The existing technology generally only replaces the plow layer soil, and replaces saline-alkali soil with cultivated soil, which cannot fundamentally achieve long-term desalination of saline-alkali soil and is easy to Cause soil to return to salt, and the selected strawberry varieties are not very salt-tolerant

Embodiment 1

[0043] A method for improving soil, reducing salt, improving fertilizer and planting strawberries in a greenhouse in a saline-alkaline area, comprising the following steps:

[0044] 1. Choose a high, dry and flat plot to build a facility greenhouse. The shed runs from east to west. The length of the shed is 70m from east to west and 8m from north to south;

[0045] 2. Laying the hidden salt discharge pipe: open a ditch in the middle of the shed along the direction of the shed. The ditch width is 30cm, the initial ditch depth is 55-60cm, and the slope is 0.5%. Lead to the drainage pipe outside the wall, and then lay salt drainage pipes perpendicular to the direction of the shed at a distance of 5m. The front end is 2m away from the main wall of the shed, and the buried depth is 50cm. At the outer drainage ditch, the hidden salt discharge pipe is a PE reticulated pipe with a diameter of 60mm. The reticulated pipe is perforated and wrapped with non-woven fabric on the outer layer...

Embodiment 2

[0053] A method for improving soil, reducing salt, improving fertilizer and planting strawberries in a greenhouse in a saline-alkaline area, comprising the following steps:

[0054] (1) Plot selection: In the coastal saline-alkali area, select plots with high, dry and flat terrain, and the average total salt content of the soil is less than 1.5%, lay out drainage ditches and build facility greenhouses;

[0055] (2) laying hidden pipes: laying salt-discharging hidden pipes in the facility greenhouse;

[0056] (3) Fertilization and plowing: spread the basic fertilizer evenly, turn and mix evenly, then rake and deep plow;

[0057] (4) Drip irrigation and rinsing: make a furrow and level the furrow surface, lay drip irrigation pipes on the furrow surface, and use the method of intermittent drip irrigation to carry out fresh water drip irrigation;

[0058] Intermittent drip irrigation: 5 days as a cycle, of which, continuous drip irrigation is 3 days, with an interval of 2 days, a...

Embodiment 3

[0070] A method for improving soil, reducing salt, improving fertilizer and planting strawberries in a greenhouse in a saline-alkaline area, comprising the following steps:

[0071] (1) Plot selection: In the coastal saline-alkali area, select plots with high, dry and flat terrain, and the average total salt content of the soil is less than 1.5%, lay out drainage ditches and build facility greenhouses;

[0072] (2) laying hidden pipes: laying salt-discharging hidden pipes in the facility greenhouse;

[0073] (3) Fertilization and plowing: spread the basic fertilizer evenly, turn and mix evenly, then rake and deep plow;

[0074] (4) Drip irrigation and rinsing: make a furrow and level the furrow surface, lay drip irrigation pipes on the furrow surface, and use the method of intermittent drip irrigation to carry out fresh water drip irrigation;

[0075] Intermittent drip irrigation: 6 days as a cycle, of which, continuous drip irrigation for 3 days, interval of 3 days, daily dr...

Abstract

The invention discloses a method for soil improvement, salt reduction, fertilization and strawberry planting in a saline-alkali area facility greenhouse. The invention belongs to the technical field of saline-alkali soil improvement and facility cultivation. The method comprises the following steps of selecting land parcels; laying concealed pipes; fertilizing and ploughing; carrying out dripping irrigation and drip washing; screening virus-free seedlings; managing after planting; and harvesting. According to the method for soil improvement, salt reduction, fertilization and strawberry planting in the saline-alkali area facility greenhouse provided by the invention, on the basis of soil improvement, salt reduction and fertilization, yield increase and quality improvement are taken as the purposes, a coastal saline-alkali soil facility strawberry original soil cultivation high-yield and high-efficiency quality improvement cultivation experiment is carried out, and soil water and salt regulation and control methods such as concealed pipe salt elimination, dripping irrigation salt reduction and negative pressure meter water control are formed through many years of production practice, so that the problems of low survival rate, poor growth vigor, low yield and the like of coastal saline-alkali area facility strawberry original soil cultivation in the prior art are solved. The method is simple, easy to operate and low in cost, the cultivated strawberries are high in yield and good in quality, economic benefits of coastal saline-alkali area facility strawberry original soil cultivation are effectively improved, and a technical support is provided for saline-alkali soil facility strawberry original soil cultivation.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement and protected cultivation, and more specifically relates to a method for improving soil in a saline-alkali area greenhouse for improving soil, reducing salt, cultivating fertilizer and planting strawberries. Background technique [0002] The total area of ​​saline-alkali soil in my country's coastal areas is about 35,700 km 2 , and most of the coastal areas are still silting up and forming land, and the area of ​​tidal flats is increasing continuously. The area of ​​newly added coastal tidal flats is about 20,000 km 2 . As an important part of saline-alkali land resources in my country, coastal saline-alkali land is mainly distributed in the coastal areas of the Bohai Sea and the Yellow Sea. Due to the influence of seawater erosion and soil parent material, the soil in this area has poor air permeability, high sodium adsorption ratio, and serious salinization in the coasta...
