Problems solved by technology

Due to the low germination rate of Leymus chinensis and the poor nutrient content of degraded grassland, traditional supplementary sowing and aerial sowing techniques are not only unfavorable for seedling management, but also difficult to meet the nutrient requirements of Leymus chinensis colonization and propagation. Therefore, the success rate of Leymus chinensis colonization not tall
Existing techniques for colonization of Leymus chinensis in degraded grasslands include no-tillage supplementary sowing, aerial sowing, etc. The objective shortcomings of these techniques are as follows: 1) It is not convenient for seedling management
The germination rate of Leymus chinensis is low, even if it germinates, it may cause a large number of seedlings to die due to insufficient water supply and other reasons; 2) The nutrient requirements of Leymus chinensis are not considered
The nutrient content such as nitrogen and phosphorus in the degraded grassland is low, and it is difficult to meet the needs of Leymus chinensis colonization and propagation; 3) The nutritional bowl made by the prior art is loose and easy to disperse, and it is inconvenient to move and transport

Embodiment 1

[0023] Embodiment 1: as Figure 1-2 As shown, the present embodiment provides a kind of nutrient pot for the colonization of Leymus chinensis in degraded grassland, including nutrient pot soil, brassinosterol aqueous solution, formula compound fertilizer and as soil bonding and nutrient pot soil are added in the nutrient pot soil Pregelatinized starch for setting substances.

[0024] Wherein, the configuration method of the brassinosterol aqueous solution is to add 10 ml of brassinosterol per 100 kg of water, and fully mix.

[0025] The preparation method of the formula compound fertilizer is to mix nitrogen fertilizer and phosphorus fertilizer according to the ratio of N:P=10:1.

[0026] The preparation method of the formula compound fertilizer is to mix the two according to the ratio of 1 g of diamine phosphate per 5.6 g of urea.

[0027] The addition ratio of brassinosteroid sterol aqueous solution, formula compound fertilizer, and pregelatinized starch in the nutritional...

Abstract

The invention discloses a nutritive bowl for field planting of leymus chinensis in deteriorated grassland. The nutritive bowl comprises nutritive bowl soil, wherein a brassinosteroid aqueous solution,formulation complex fertilizer and pregelatinized starch as a soiling bonding and nutritive bowl setting substance are added in the nutritive bowl soil; the success rate of field planting and expanding propagation of the leymus chinensis can be effectively improved, centralized management at seedling stage is facilitated and the utilization rate of the seeds and the survival rate of seedlings areimproved; rapid planting of the leymus chinensis in the deteriorated grassland and functional reconstruction of an ecological system are promoted; sufficient nutrients of the nutritive bowl can meetthe demands of field planting and expanding propagation of the leymus chinensis; once a cultivated nutritive bowl is transplanted to the deteriorated grassland, a large grassy field can be quickly restored by means of the advantages of colonizing division and integration of the leymus chinensis; by adopting the pregelatinized starch as a bonding and setting substance, the nutritive bowl is not easy to loosen or disintegrate, and the seedling stage management, movement, transportation and transplanting are facilitated.

Description

technical field [0001] The invention relates to a nutrient bowl, in particular to a nutrient bowl used for the colonization of Leymus chinensis in degraded grassland. Background technique [0002] The recolonization of constructive species is an important goal of functional restoration of degraded grasslands. Leymus chinensis is one of the construction species of typical grasslands and meadow steppes in China. Due to the low germination rate of Leymus chinensis and the poor nutrient content of degraded grassland, traditional supplementary sowing and aerial sowing techniques are not only unfavorable for seedling management, but also difficult to meet the nutrient requirements of Leymus chinensis colonization and propagation. Therefore, the success rate of Leymus chinensis colonization not tall. Existing techniques for colonization of Leymus chinensis in degraded grasslands include no-tillage supplementary sowing, aerial sowing, etc. The objective disadvantages of these tech...
