Method of high yield cultivation of wild rice shoots in tropic region

Abstract

The invention provides a method of high yield cultivation of wild rice shoots in a tropic region. The method comprises the following steps of: (1) variety selection and wild rice shoot seed screening:adopting the double cropping wild rice shoots, (2) seedling raising: cutting off overground parts, storing seed wild rice shoot stumps with soil in a refrigerator at 0-5 DEG C for 1-3 months, takingthe seed wild rice shoot stumps out for seedling raising, (3) wild rice shoot field selection and base fertilizer treatment: applying 3-4 ton pig manure or chicken manure and 8-10kg three-nutrient compound fertilizer per mu before field planting, (4) field planting: performing shallow water irrigation before the field planting and planting at density of 1100-1300 wild rice shoots per mu, row spaceof 0.8-1.2m and planting distance of 0.4-0.6m, (5) field management: drying a field for a week a week after the field planting, performing the shallow water irrigation and drying the field separatelyfor a week, performing deep water irrigation till harvesting, and spraying 472.5g of fenaminosulf per mu for twice per week, (6) disease and pest control, and (7) timely harvesting. The method achieves a yield per mu of the wild rice shoots in the tropic region to reach above 3500kg; the wild rice shoots can be harvested in January and February in winter; and the method solves the problem of undersupply of main producing areas of the wild rice shoots in the winter.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a method for high-yield cultivation of wild rice stems in tropical regions. Background technique [0002] Zizania latifolia (Griseb.) Stapf is a unique aquatic vegetable in my country. It has high nutritional value and is known as "water ginseng". Traditional Chinese medicine believes that Zizania is mainly used to treat abdominal pain due to summer heat and dampness, chronic heat in the middle burner, polydipsia, dyspepsia, alcohol poisoning, and insufficient milk. At present, the planting is mainly concentrated in the middle and lower reaches of the Yangtze River provinces, such as Zhejiang, Jiangsu, Anhui, Fujian, Hubei and other provinces. Jiangsu and Zhejiang are the most fond of wild rice stems. There is a saying in the market that "it is better to be without meat for a day than to be without wild rice stems for a day." There are many varieties of Zizania ...

AI Technical Summary

Problems solved by technology

Therefore, at present, the introduction of Zizania zazaza in the tropics either fails, or the yield cannot be compared with the main producing areas. After analysis, its main problem is that the existing cultivation techniques are not suitable for the climate and soil characteristics in the tropics. The present invention will provide a A high-yield method for planting wild rice stems in tropical areas. With this method, the yield of wild rice stems in tropical regions will reach and exceed that of the main production areas, and it will also be possible to market wild rice stems around the Spring Festival, filling the market for wild rice stems in winter.
