Embodiment 1

[0042] A method for high-yield cultivation of wild rice stems in tropical areas, comprising the steps of:

[0043] (1) Variety selection and Zizania seed screening

[0044] Select Shuangjizao "Zhejiao No. 6" for division propagation, and select seedlings with strong tillering, fat, white and tender water, no male and gray water, and no disease;

[0045] (2) Nurturing

[0046] Store the seedling pier with the ground part cut off and with soil in a cold storage at 0°C for 1 month, take it out and place it in a nursery field for seedling cultivation; the seedlings in the seedling field will grow to 5-10 cm, and each seedling pier will be tilled. Up to 40 to 80 trees, split the seedling pier with a sharp knife, divide it into several small pier, and keep 15 tillering seedlings for each pier;

[0047] (3) Selection of wild rice fields and basal fertilizer treatment

[0048] Choose paddy fields with convenient water supply and drainage and good fertility for planting Zizania; bef...

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 ...
