At present, the use of vegetable stalks and rotten fruits in many vegetable growing areas is low. Most farmers directly stack them in the sun drying around the shed, and then collect the burning treatment, and some directly discarded on the roadsides and rivers, which not only cause nutrient resources. Losses also cause environmental pollution. The nutrient content of nitrogen, phosphorus and potassium in vegetable straw is higher than that of wheat and corn stalk. It has high moisture content and is easily decomposed. It is a good raw material for composting, but it is difficult for vegetable farmers to kill the vegetable pathogen. The use of high-temperature compost can make full use of nutrients and moisture of vegetable straw, and can quickly and completely eliminate harmful pathogenic bacteria and realize harmless treatment. The compost produced has a higher carbon-nitrogen ratio and an increased organic matter content compared with that of ordinary livestock and poultry manure. Long-term application of compost can increase soil nutrient holding capacity, and has sustained release properties. Compost can also significantly improve the granule structure of the soil and prevent soil compaction. Therefore, composting vegetable stalks or rot fruit is an effective way to rationally utilize vegetable stalks, harmlessly dispose of and treat agricultural wastes, and has important significance for the safe and clean production of vegetables. The compost material is proportioned according to certain conditions, the moisture content of the material is between 55% and 65%, and the ratio of carbon to nitrogen is 25:1-40:1, the pH is 4-6, and the best is about 7.5. The composting process needs to control the temperature rise, the heating stage of the medium temperature, the high temperature stage and the cooling stage of the cooling and post-harvest, and obtain the compost. The specific operation method of vegetable straw high-temperature composting: 1. Select the venue. In the free space next to the greenhouse, dig 1.5-2 meters wide, 0.5-1 meters deep, and the length of the pit depends on the amount of compost material; or on a flat ground, tap a 0.5-1 meter high brick to cement the concrete pool. . 2. Crush the straw. Before the composting, remove the ropes, iron wires and other items from the vegetable stalks. In order to speed up the decomposing and shorten the composting time, the vegetable straw, corn stalks or other crop stalks are cut into small pieces of less than 5 cm. In particular, the content and the degree of lignification of the pepper stalks are high. The compost must be crushed with a grinder to speed up the process. Decomposing speed. 3. Materials and ratios. Tomato stalks or pepper stalks, corn stalks, and fresh chicken manure were mixed in a ratio of 1:1:1 to 2:1:1 to adjust the moisture content of the material to 55%-65%. The sensory judgement is that the material is hand-picked and water drips from the material but does not flow. In order to speed up the temperature rise and decomposition of the material, straw ripening agents can be added, such as straw decomposing bacteria, "301" inoculant, rot straw spirit, "HEM" bacteria, enzyme bacteria, VT fungicides, etc. The dosage is about 5 kg. Fresh chicken manure can also be replaced with urea (or 200-300 kg of decomposed manure) to meet the nitrogen required for microbial fermentation. 4. Method of composting. The width of the bulk body is generally required to be 1.6-2 meters, the height of the pile is 1-1.5 meters, and the length is determined by the amount of material and the size of the site. The materials can be mixed into the compost pool, or they can be layered. Generally, they can be stacked in 3 layers. The first and second layers are each 40 centimeters thick, and the third layer is 20 centimeters thick. The layers are evenly distributed between the layers and the third layer. The ratio of the mixture of straw decomposition agent and fresh chicken manure, straw decomposition agent and fresh chicken manure was 4:4:2 from bottom to top. After being piled up, seal with mud or cover with plastic sheeting. During the composting period, the temperature of the bulk body rises rapidly, and the temperature is kept between 65° C. and 70° C. for about 10 days. The composting is carried out on the tenth and the tenth days of composting respectively. Composting can continue for 20 to 25 days to complete the detoxification treatment. , and continue to compost for about 10 days, after the completion of the maturity phase can be returned to the field.
