Problems solved by technology

my country's saline-alkali land has been gradually recognized and developed by people, but the degree of development is limited, and many crops cannot be effectively planted in saline-alkali land
[0003] At present, many coastal saline-alkali lands are used to grow various saline-alkali-tolerant crops, but there are many obstacles to the cultivation of common crops, making it difficult to grow effectively
Suaeda cinerea has a certain ability of salt-alkali tolerance, but there are still problems such as low survival rate in large-scale planting; while rapeseed is planted in saline-alkali soil, it basically cannot grow normally, and rapeseed has high economic value and nutritional value
[0004] The planting of Suaeda cinerea and rapeseed in the prior art has the following defects: (1) the survival rate of Suaeda cinerea planting is not high enough, and the yield is not high; (2) the survival rate of rapeseed in saline-alkali soil is very low, and the yield is also very low (3) The existing technology is difficult to improve saline-alkali land while planting Suaeda cinerea and rape in saline-alkali land

Embodiment 1

[0024] Embodiment 1 The interplanting method of Suaeda cinerea and rapeseed in a kind of saline-alkali land

[0025] Step 1. Select the saline-alkali land in the planting area

[0026] The selected planting area is sandy soil with severe coastal salinization, the salt content of the 0-30cm soil layer is 1.0-1.3%, the pH is 8.3-8.5; the total porosity of the soil is 28-30%, and the soil bulk density is 1.9-2.1g / cm 3 , In the soil, there is a serious lack of various nutrients.

[0027] Step 2. Preparation before planting

[0028] (1) Preparation of decomposing agent

[0029] a. Cultivate Pseudomonas fluorescens, Pediococcus pentosacea, Bifidobacterium longum, and Trichoderma koningeni respectively, and the culture medium is centrifuged to obtain a bacterial suspension, which is combined and evenly sprayed onto potato starch to obtain a composite microbial powder;

[0030] The content of the bacteria in the composite microorganism powder is: Pseudomonas fluorescens 20...

Embodiment 1

[0056]Adopt the planting method of embodiment 1, only change the planting step, change the planting step to: only plant Suaeda cinerea, the planting distance is 18cm, and the row spacing is 30cm; other planting methods are carried out by the method of embodiment 1.

Embodiment 2

[0058] Adopt the planting method of embodiment 1, only change the planting step, change the planting step to: only plant rapeseed, the planting spacing is 10cm, and the row spacing is 15cm; Other planting methods are carried out by the method for embodiment 1.

[0059] Planting results:

[0060] (1) Adopt the present invention to plant Suaeda cinerea and rape in the middle of saline-alkali land for 1 year, and record the planting results:

[0061] Suaeda cinereus: high planting survival rate, high yield, and excellent quality; the survival rate of Suaeda cinereus planting is 99%, the yield of harvested young shoots of Suaeda cinereus is 1.2 tons, and the protein content of fresh stems and leaves is 2.25 %, the crude fiber content is 18.64%, and the fat content is 0.49%; compared with comparative example 1: the survival rate improves by 14%, the average yield per mu improves by 19%, the protein content of fresh stems and leaves improves by 13.1%, and the crude fiber content i...

Abstract

The invention provides an interplanting method of suaeda glauca bge and oilseed rape in saline-alkali soil, and the method comprises the steps of preparation before planting, planting, fertilizing and managing, wherein the planting step is carried out according to the following requirements: an interplanting ratio of the suaeda glauca bge and the oilseed rape is 3 to 5, and the suaeda glauca bge and the oilseed rape are planted in a same field. The planting step comprises the steps of planting the suaeda glauca bge: soaking seeds in a potassium permanganate solution of 500mg / l for 15 minutes before seeding, soaking the seeds in clean water of 40 DEG C for 3 hours; planting 3 rows in each field, wherein a seeding row spacing is 30 cm; when 6 true leaves grow out, thinning, so as to enable the row spacing to be 18 cm. The planting step also comprises planting the oilseed rape: during the last ten days of March, transplanting the oilseed rape of 3 to 4 leaves into the field, wherein the plant spacing is 10 cm, and the row spacing is 15 cm. By adopting the interplanting method of the suaeda glauca bge and the oilseed rape in saline-alkali soil, the survival rate of the planted oilseed rape is 96.2 percent, and the rapeseed yield per mu is 496kg.

Description

technical field [0001] The invention belongs to the field of planting methods in saline-alkali land, and relates to a method for interplanting plants in saline-alkali land, in particular to a method for interplanting Suaeda cinerea and rape in saline-alkali land. Background technique [0002] Saline-alkali land mainly refers to salinized soil with high chloride or sulfate content. The soil is alkaline, but the pH value is not necessarily high. Or, soils that contain carbonates or biphosphates, have a higher pH and make the soil more alkaline. Saline-alkali land has less organic matter content, low soil fertility, poor physical and chemical properties, and many anions and cations harmful to crops, making it difficult for crops to grow. my country's saline-alkali land has been gradually recognized and developed by people, but the degree of development is limited, and many crops cannot be effectively planted in saline-alkali land. [0003] At present, many coastal saline-alka...
