Cultivation method allowing water bamboos to be harvested continuously in summer and autumn

Abstract

The invention provides a cultivation method allowing water bamboo to be harvested continuously in summer and autumn. The method includes the steps that (1), Liu tan water bamboos and a good 86-1strain water bamboo variety which can be used in summer and autumn are selected; (2), seedling raising and growing: seeds are taken in January and transplanted in a seedling raising field, and a small shed or a mulching film is adopted for covering; (3), big field planting: big mound planting is adopted; (4), water slurry managing: planting in shallow water, water bamboo plant cultivating in deep water and tillering in shallow water are carried out, the depth is increased step by step in the middle and later periods, and shallow water and deep water are combined in the water bamboo harvesting period; (5), field raking, weeding and fertilizer applying: the field raking is performed three times at the interval of 7-8 days in combination with tillering fertilizer applying from shallow to deep; (6), irrigation with circulating water: in the high temperature period from June to July, irrigation is carried out in a circulating mode to lower the temperature of the field and increase oxygen supply; (7), harvesting in time: summer water bamboos are harvested from late May to middle July, and autumn water bamboos are harvested from late September to middle October; (8), water bamboo plant clearing and yellow leaf removing: before pregnant water bamboo fertilizer is applied for the first time from the end of July to the beginning of August, and yellow leaves at the bases of water bamboo plants are removed through pulling and stepped into the slurry as fertilizer to facilitate growth of the autumn water bamboos; (9), after the autumn water bamboos are harvested, stubble cleaning is performed in time. The cultivation method overcomes the defect that water bamboo pregnancy is not suitable in the high temperature period, two batches of water bamboos can be harvested in summer and autumn, the yield is high, and benefits are good.

Description

technical field [0001] The invention provides a cultivation method for continuously harvesting bamboo shoots in summer and autumn, and belongs to the technical field of plant cultivation. Background technique [0002] Wuxi’s summer-autumn mixed-use type of second-ripening water bamboo, the traditional cultivation method is generally planted and harvested in the first season of autumn water, with a yield of about 800 kg per mu, and summer water can only be harvested in the early summer of the second year, with a yield of about 1,000 kg per mu. The disadvantages of this method are: The period is long, the annual output is low, the land output rate per unit area is low, and the marketing period of wild rice stems is concentrated, and the economic benefits are not high. Contents of the invention [0003] The invention provides a cultivation method for continuously harvesting Zizania in summer and autumn, which can overcome the above-mentioned defects, increase yield and improv...
