Plant liquid, and preparation method and application thereof

Abstract

The invention discloses a plant liquid, and a preparation method and an application thereof. The preparation method comprises the following steps: adding 50-60g of Folium Isatidis and 20-25g of fresh leaf wastes to every 20g of the fresh branch and leaf material of Melaleuca ahemifolia, adding 1200mL of distilled water, boiling, adding water to 1200mL, and removing residues to obtain a supernatant which is the plant liquid. The plant liquid can promote growth of crops, substantially increases yield, substantially reduces pest diseases of the crops, and makes leaves be green to realize the plant foliage beautifying effect; and the plant liquid also can substitute chemical fertilizers and parts of chemical pesticides to prepare plant green manure for improving the mouthfeel of the crops, so the procurement price of the crops is improved. The plant liquid contains a large amount of various organic matters, and increases the organic matters of soil, so the activity ability of soil microbes is enhanced, and some residua pesticides, heavy metals and other pollutants in the soil are adsorbed, thereby the poisoning effect of poisonous and harmful substances on soil and crops is alleviated.

Description

Technical field: [0001] The invention belongs to the fields of crop planting and environmental protection, and in particular relates to a plant liquid, a preparation method thereof and an application in the fields of crop beauty, green manure preparation and environmental protection. Background technique: [0002] At present, due to the severe damage to the agricultural ecological environment in China, crop diseases and insect pests are becoming more and more serious, and the leaf surface and leaf color of crops are damaged by diseases and insect pests, resulting in loss of crop yield, and the selling price is also low, especially for vegetable crops, which has led to planting industry suffered serious losses. In addition, the abuse of chemical pesticides, chemical fertilizers and other non-environmentally friendly fertilizers has also aggravated the agricultural ecological crisis, directly threatening the health of the people and the sustainable development of the economy a...
