Mixed sowing method of switchgrass and wild soybean in saline-alkali land

Abstract

The invention belongs to the technical field of ecological agriculture and particularly relates to a mixed seeding method for switchgrass and wild soybeans in saline-alkali land. The mixed seeding method is achieved through the following steps that firstly, after the saline-alkali land is ploughed and raked to be flat, mixed fertilizer composed of farmyard manure and erythromycin waste residues is applied to the saline-alkali land, and ridging is performed; secondly, switchgrass seeds and wild soybean seeds are placed in a seed processing agent in advance to be soaked for 8-10 min, hole sowing is performed on ridges, the wild soybean seeds are sown first, the switchgrass seeds are sown after soil covering, and soil covering and filling are performed so that the saline-alkali land can be flat; thirdly, normal field management is performed after sowing. According to the method, the switchgrass seeds and the wild soybean seeds are wrapped through the seed processing agent so that the seeds can be prevented from being eroded; meanwhile, germination of the seeds is accelerated, the germination rate and the germination potential are increased, the seeds are good in quality, operation is easy and fast, a large amount of manpower and a larger number of material resources are saved, the two crops cooperate with each other, growth is mutually promoted, stability is good, and high-quality forage grass is provided for development of animal husbandry in China.

Description

technical field [0001] The invention belongs to the technical field of ecological agriculture, and in particular relates to a method for mixing switchgrass and wild soybean in saline-alkali land. Background technique [0002] Switchgrass (Panicum virgatum L.) belongs to the Gramineae family and is often used for grazing, ecological construction, and ethanol production. It is a new type of energy plant. Wild soybean (Glycine soja Sieb.et Zucc) belongs to the leguminous family and has excellent characteristics such as salt-alkali tolerance, drought resistance, and disease resistance. [0003] Different types of saline-alkali soils are distributed from lowlands to plateaus in my country, which seriously restricts the development of agriculture. The establishment of artificial grassland is an important measure for the development of intensive grassland animal husbandry, the implementation of ecological restoration and system reconstruction, and sustainable development strategie...

Problems solved by technology

The establishment of artificial grassland is an important measure for the development of intensive grassland animal husbandry, the implementation of ecological restoration and system reconstruction, and sustainable development strategies. Mixed sowing of beans and grasses can not only improve the nitrogen nutrition balance of grassland ecosystems, but also improve the quality and yield of grasslands, improve Soil environment, but mixed sowing grassland often has problems such as poor pasture growth, fierce interspecific competition, and poor community stability due to improper combination

In the prior art, when seeds are directly broadcast or mixed crops are used in saline-alkali land, the emergence rate is low, the survival rate is low, and the seedlings are weak. Most of the seeds are cultivated into seedlings in advance, and then transplanted. The process is cumbersome and consumes a lot of manpower. material resources

At present, there is no report on the mixed planting of switchgrass and wild soybean
