Water storage irrigation system and growth method of ecological safety type resistant starch rice

Abstract

The invention discloses a water storage irrigation system of ecological safety type resistant starch rice. The water storage irrigation system comprises a water storage pool and an irrigation canal; awater inlet pipe and a water outlet pipe are arranged on the water storage pool, and a first volcanic rock layer is laid at the bottom of the water storage pool; and one end of the irrigation canal is communicated with the water outlet pipe of the water storage pool, and the other end of the irrigation canal extends to a rice planting field. The invention also discloses a growth method of the ecological safety type resistant starch rice. The growth method is based on the water storage irrigation system and comprises the following steps of irrigating and immersing planting land soil for threedays by using irrigation water of the water storage pool; conducting water draining, and drying the field for five days; conducting soil preparation, and adding a soil remediation agent and an organicfertilizer into the soil, wherein 50%-70% of the soil remediation agent and the organic fertilizer are kept between 15 cm and 25 cm on the surface layer of the soil, and the rest 30%-50% of the soilremediation agent and the organic fertilizer are kept between 0 cm and 15 cm on the surface layer of the soil; transplanting resistant starch rice seedlings into the soil; and applying tillering fertilizer after the resistant starch rice seedlings are transplanted for 5-7 days. According to the growth method of the ecological safety type resistant starch rice, pesticide residue heavy metal is reduced, and the method is environmentally friendly and safe.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a water storage irrigation system and a growth method for ecologically safe resistant starch rice. Background technique [0002] Resistant starch rice is a special kind of rice. Resistant starch can resist amylase hydrolysis in the human body, and will not be digested and enzymolyzed by the stomach and small intestine. It will be fermented and degraded in the large intestine to produce butyrate substances, which in turn can help middle-aged and elderly people Regulate blood sugar and improve intestinal environment. [0003] At present, the abuse of chemical fertilizers and pesticides has caused serious soil and water damage. Many soil and water continue to be planted, producing crops with low yields and excessive heavy metal content. The crops grown are not safe to eat. Contents of the invention [0004] The object of the present invention is to provide a water storage i...
