Water-hyacinth biological coverage method for corn planting

Abstract

The invention discloses a water-hyacinth biological coverage method for corn planting. The water-hyacinth biological coverage method comprises the operating steps of: (1) harvesting water hyacinth; (2) cleaning weeds and sludge carried on water hyacinth plants, and then draining; (3) cutting the water hyacinth into crushed blocks; (4) airing the crushed blocks of the water hyacinth; (5) when 3-4 new leaves grow on each corn seedling, covering the crushed blocks of the dried water hyacinth on the surface of the soil of line gaps of corn plants by the amount of 4-6kg / m<2> with the covering thickness of being 18-22cm. The water-hyacinth biological covering method disclosed by the invention not only has the advantages by utilizing biological coverage, but also is more economic and practical than the use of artificially-synthesized plastic covering materials since biomass is used as organic covering materials.

Description

technical field [0001] The invention relates to the fields of crop cultivation and biomass resource utilization, in particular to a water hyacinth biological covering method for corn planting. Background technique [0002] Corn is considered one of the most popular food crops in China. Traditional agricultural management techniques used to increase corn yields include irrigation, tillage, and fertilization. But in recent years, soil covering technology has been used more and more. Soil mulching has many advantages, such as delaying soil moisture loss, moderating soil temperature changes, inhibiting weed growth, providing soil with organic matter and nutrients, enriching soil microbial communities, and increasing crop yields. For example, the average daily soil temperature of covered soil is 2-9°C higher than that of uncovered soil, especially in the early stages of crop growth. In terms of water retention, soil cover is mainly reflected in the fact that the cover can sign...

Problems solved by technology

At the same time, due to the characteristics of water hyacinth itself and the increasingly serious water pollution, water hyacinth has grown wildly, causing serious social, economic and environmental problems, such as blocking rivers, affecting irrigation, destroying water conservancy facilities, and causing river silt accumulation; The biodiversity of the water body is reduced, which reduces the production of fisheries; spreads diseases and insect pests, etc.

A large amount of water hyacinth waste is often discarded due to the lack of effective recycling technology. The high load of organic matter will cause surface runoff, scouring and underground seepage through rainfall to pollute surface water and groundwater, which greatly threatens the water environment and human health and safety.

[0005] Therefore need to develop a kind of can not only effectively solve the water hyacinth pollution problem, but also utilize water hyacinth to improve the biological covering method of crop yield, but so far, water hyacinth is used as the biological covering of corn planting process and has not been reported yet
