Problems solved by technology

Mixed sowing of beans and grasses can not only improve the nitrogen nutrient balance of the grassland ecosystem, but also improve the quality and yield of the grassland, and improve the soil environment. However, the mixed sowing of grasslands often results in poor plant growth and intense interspecific competition due to unreasonable planting methods or improper variety combinations. , Poor community stability and other issues

Embodiment 1

[0031] 1) Preparation of base fertilizer: 100 parts of farmyard manure, 85 parts of monosodium glutamate leftovers, 55 parts of bagasse and 28 parts of traditional Chinese medicine dregs were used as the fermentation base material, the water content was adjusted to 22% by mass fraction, and 3 parts of cellulase and 2.5 parts of Mixed fermentation of yeast at 22-27°C for 3 days, then add 0.9 part of Bacillus subtilis, 0.5 part of Azospirillum and 0.4 part of Aspergillus niger as fermentation bacteria, and aerobic fermentation at 25-37°C for 10 days;

[0032] Farmyard manure is chicken manure;

[0033] The traditional Chinese medicine residue is a mixture of dodder, dandelion, mugwort leaves, bamboo yellow, unicorn lotus, grass aconitum, snake vine, araceae, burnet and aconite.

[0034] 2) Preparation of seed treatment agent: It is prepared by mixing 3 parts of diethylhydrazide, 3 parts of ascorbic acid, 1.5 parts of azone, 1.2 parts of Bacillus sporogenes, 5.5 parts of sucrose ...

Embodiment 2

[0036] A kind of saline-alkali soil switchgrass and wild soybean mixed sowing planting technology, comprises the following steps:

[0037] 1) Land consolidation

[0038] The saline-alkali land is leveled by rotary tillage, and the soil particle size is 2-5mm, and the base fertilizer of Example 1 is applied at 280kg / mu, and then rotary tillage and rake level again;

[0039] 2) Switchgrass seedling cultivation

[0040] For seedling cultivation in early March, first spray the switchgrass seeds with water to moisten them, then fumigate them with garlic oil for 8 minutes, soak them in the seed treatment agent for 5 minutes, and then raise seedlings in plug trays with a seeding rate of 2.6kg / mu; in early May, dig holes and transplant them horizontally The distance between the holes is 1.5m, the distance between the vertical holes is 1m, the hole depth is 10cm, and the diameter of the upper opening is 10cm. :1.5, finally cover with soil and fill up;

[0041] 3) Sowing of wild soyb...

Embodiment 3

[0046] A kind of saline-alkali soil switchgrass and wild soybean mixed sowing planting technology, comprises the following steps:

[0047] 1) Land consolidation

[0048] The saline-alkali land is leveled by rotary tillage, and the soil particle size is 2-5mm, and the base fertilizer of Embodiment 1 is applied at 250kg / mu, and then rotary tillage and rake level again;

[0049] 2) Switchgrass seedling cultivation

[0050] At the beginning of March, seedlings were grown in plug trays, with a seeding rate of 3kg / mu; at the beginning of May, holes were dug for transplanting, the horizontal hole distance was 1.5m, the vertical hole distance was 1m, the hole depth was 10cm, and the diameter of the upper opening was 10cm, and the roots of switchgrass clusters were placed in the holes. , cover soil and fill up;

[0051] 3) Sowing of wild soybeans

[0052] The wild soybean seeds were soaked in the seed treatment agent for 8 minutes, and then sowed on-demand between the rows of switch...

Abstract

The invention relates to a panicum virgatum and wild soybean mixed seeding technology for saline-alkali soil. The panicum virgatum and wild soybean mixed seeding technology for the saline-alkali soil has the advantages that by means of seed pretreatment, scientific and reasonable mixed seeding, intermission seeding and the like, seed germination and growth are promoted effectively, and high survival rate, strong stress resistance, high product yield, high quality and the like are achieved; panicum virgatum is harvested from the end of the July to the beginning of the August, thereby being higher in palatability; fresh panicum virgatum yield increases by 10% and reaches 500-3800 kg / mu, and crude protein content increases from 7% to 10%; the panicum virgatum and wild soybean which are subjected to mixed seeding are synergistic and capable of promoting mutual growth, high stability is achieved, high-quality forage grass is provided for development of the animal husbandry of China, and the technology plays an active driving role in development and utilization of the saline-alkali soil and biomass energy popularization.

Description

technical field [0001] The invention belongs to the technical field of ecological agriculture, and in particular relates to a mixed planting technique of switchgrass and wild soybean in saline-alkali land. Background technique [0002] Switchgrass belongs to the Gramineae family and is a perennial plant that grows rapidly and survives easily in plains. It can be divided into two ecological types: lowland type and highland type. It is often used for grazing, ecological construction and ethanol production. It is a new type of plant. energy plant. Wild soybeans belong to the leguminous family, and the whole plant is a favorite feed for livestock, and can be planted as pasture, green manure and soil and water conservation plants. It has excellent characteristics such as salt-alkali tolerance, drought resistance, and disease resistance. [0003] The content of organic matter in saline-alkali land is low, the soil fertility is low, the physical and chemical properties are poor, ...
