Description
Technical Field
The invention relates to the technical field of cyperus esculentus production, in particular to application of inositol in improving the yield of the cyperus esculentus.
Background
The import of soybean in China accounts for about 2/3 of global trade volume, the import dependence is 87%, the import dependence accounts for 2/3 of export of agricultural products in China in the U.S., and the soybean and edible oil are large-volume agricultural products with the largest import volume, the largest consumption and the highest import dependence in China and have high external dependence. The soybean in China is a conventional variety, the single yield is lower than 25% in the United states, the oil content is lower than 2%, the cost is high by 40%, and the price of acquisition price is 0.6 yuan/kg higher from import to bank. Therefore, on the premise of guaranteeing farmland red lines, the method for exploring and replacing imported soybeans and supplementing high-quality resources of domestic oil sources becomes a selection and necessary way for coping with current dilemma and preempting future industry high points.
Compared with other crops, the cyperus esculentus (academic name: cyperus esculentus L.) is the most competitive oil crop for replacing imported soybeans and supplementing domestic oil sources. The yield per mu of the improved variety of the cyperus esculentus is generally 500-600kg, the oil content is 20-25%, the oil yield per mu is more than 120 kg, and the oil yield per unit area is 5 times of that of the soybean and 2 times of that of the rape. The cyperus esculentus is suitable for desertification of the marginal land, and the half desert marginal land of at least 4-5 hundred million mu in China is suitable for planting the cyperus esculentus, so that a considerable increment for future further expansion is provided for expanding the cultivated area.
However, the cyperus esculentus planted in the market at present is self-bred for many years, so that the variety is seriously mixed and degenerated, the single yield is low, and the mu yield is about 400 kg. If the yield of the cyperus esculentus can be further improved, the cyperus esculentus has important significance in the edible oil supply crisis. The cyperus esculentus is a asexual propagation crop, and at present, the variety breeding is only carried out by the technologies of radiation mutagenesis, chemical mutagenesis, mutant mutagenesis and the like, but sexual hybridization breeding cannot be carried out yet, and the variety breeding is time-consuming and labor-consuming. Chemical regulation cultivation is an emerging technology in agricultural production, is widely applied to crops, and plays a positive role in coping with the crisis of edible oil supply if the yield of the cyperus esculentus can be further improved by using a chemical regulation means and promoted and applied in a large area. Inositol (myo-inositol) is a small molecular hormone which is widely used in animals and plants and is involved in the growth and development of plants, synthesis of cell walls, mineral storage, signal transduction and other processes. The research on the improvement of plant yield of inositol also belongs to the blank, and the research adopts exogenous inositol treatment to improve the yield of the cyperus esculentus, so that a new way is opened up for promoting the development of the cyperus esculentus industry.
