Abstract

The invention discloses a greenhouse cultivation method for organic zizania latifolia. The method includes the following aspects: (1) selecting a planting pond, choosing a flat area far away from an industrial area and a living area and closes to a stream located at the foot of a mountain to build a greenhouse, enabling the planting pond in the greenhouse to run east and west, sealing the greenhouse, and performing atomization treatment; (2) selecting planting soil, taking lotus pond mud, river mud and marsh pond mud, after natural drying is performed, performing mixing, performing sterilization, adding organic matter and a mixed microbial inoculants, performing mixing, and performing fermentation; (3) performing planting, cutting a zizania latifolia cluster with 5-7 zizania latifolia seedlings, soaking the cut zizania latifolia cluster into clear water and a sodium hypochlorite solution in sequence, and performing transplanting at the middle of March to the end of the March; (4) performing cultivation in the greenhouse, after planting is performed, adjusting the water depth and temperature of the planting pond, enabling the volume concentration of carbon dioxide to be improved, and performing regular spraying by using a plant bactericide and a microelement solution; and (5) performing breeding and performing harvesting, putting carassius auratus fry in the beginning of May, after harvesting is performed at the middle of July to the beginning of August, discharging water, and applying an organic fertilizer, a plant bactericide and a microelement solution.

Description

technical field [0001] The invention belongs to the technical field of organic rice stem cultivation, and in particular relates to a greenhouse cultivation method for organic rice stem.

Problems solved by technology

[0003] The present invention aims at the existing problems: planting Zizania in paddy fields has a high rate of damage by diseases and insect pests, large amount of pesticide usage, and the soil and water close to industrial and living areas are easily polluted by heavy metals, and there is a potential risk in the safety of Zizania eating; with economic development, With the improvement of living standards, people's demand for organic wild rice stems is increasing day by day, but under natural conditions, planting is affected by water, temperature and other conditions, and the yield of organic wild wild rice stems is small, which cannot meet market demand
