Farm manure for planting lotus roots and preparation method thereof

Abstract

The invention discloses farm manure for planting lotus roots and a preparation method thereof. The farm manure for planting the lotus roots is prepared from the following raw materials: cow dung, fowlmanure, pig manure, pond mud, soybean pods, quick lime and corn distillers' grains; the preparation method comprises the following steps: adding the quick lime into livestock manure and mixing and reacting for 30 to 60min; then adding the pond mud; after uniformly mixing, drying and crushing to obtain manure powder; mixing the manure powder, the soybean pods and the corn distillers' grains and putting a mixture into a fermentation tank; carrying out first-time anaerobic fermentation, aerobic fermentation and second-time anaerobic fermentation in sequence to obtain the farm manure for plantingthe lotus roots. The farm manure for planting the lotus roots, provided by the invention, has the characteristics of complete composting, sufficient sterilization, simple production technology, goodfertilizer efficiency and the like.

Description

technical field [0001] The invention relates to the field of farmyard manure preparation, in particular to a farmyard manure used for planting lotus root and a preparation method thereof. Background technique [0002] Lotus root is a perennial root-type aquatic herb of Nymphaeaceae, which is native to my country and India, and is cultivated in Japan, Southeast Asia, India, and Africa. According to the adaptability to the depth of the water layer, it can be divided into shallow water lotus root and deep water lotus root. Lotus root is eaten as a swollen underground rhizome, commonly called lotus root. [0003] Lotus root is a fertilizer-loving aquatic crop with strong fertilizer tolerance. The lotus root field should be applied with sufficient base fertilizer. The base fertilizer (base fertilizer) is mainly organic fertilizer, and there are many types of organic fertilizer, including crop straw, humic acid fertilizer, microbial fertilizer, farm manure, compound fertilizer a...

Problems solved by technology

[0005] However, farmyard manure also has the following disadvantages: 1. Livestock farmyard manure contains bacteria and pests such as Escherichia coli and nematodes. Direct use will cause the spread of diseases and insect pests, crop disease, and also affect the health of people who eat agricultural products. When the lotus root is planted, bacteria such as E. coli will pollute the surrounding water with the irrigation water, and the spread of the bacteria will be wider; 2. Most of the nutrients in the unfermented and decomposed farmyard manure are in an organic state or a slow-acting state, which cannot be directly absorbed and utilized by crops. Only when it is decomposed and transformed into a quick-acting state can it be absorbed and utilized by crops. Therefore, direct application of farmyard manure without fermentation will slow down the fertilizer effect
