Embodiment 1

[0019] The safe application method of cucumber biogas slurry water and fertilizer integration in this facility is winter and spring cropping cucumbers. The test site is Yangmiao Village, Yugou Town, Huaiyin District, Huai'an City, Jiangsu Province. The cucumber variety is Jinyou 36, and the cucumber planting area in the test shed is 0.76 mu. The planting area of ​​cucumbers in the shed is 0.76 mu for conventional planting management, and the steps include:

[0020] On August 15th, the top membrane of the facility greenhouse was covered, and the high-temperature braising shed was flooded with biogas slurry to keep the biogas slurry level 2-3cm above the soil layer;

[0021] On September 30th, 70 kg of superphosphate, 30 kg of potassium sulfate, 10 kg of magnesium sulfate, and 5 kg of ferrous sulfate were added per mu during land preparation;

[0022] The number of cucumber seedlings planted is 3419 (equivalent to 4499 plants / mu), the plant spacing is 20 cm, the small row spacin...

Abstract

The invention discloses a method for safely applying biogas slurry, water and fertilizer integration of facility cucumbers. The steps include covering the top film of facility greenhouses and flooding the high-temperature stewed sheds with biogas slurry; adding fertilizer when preparing the ground before planting cucumbers; watering cucumber seedlings once after planting Slow seedling water: After the cucumber seedlings grow to 12 leaves, start to water the biogas slurry and water until 7 days before harvesting and pulling the seedlings. Water the biogas slurry first and then water each time. The application rate is 4 tons of biogas slurry per mu, 6 tons Water, water with high calcium and high potassium dissolved in fertilization. In the invention, the biogas slurry is filtered and directly used for irrigation of cucumber greenhouses, so that the biogas slurry can be irrigated first and then clear water or water and fertilizer can be irrigated, which saves manpower. It also saves the step of flushing the biogas slurry pipeline with water, avoids the phenomenon of microorganism breeding and blocking the pipe network, and further strengthens the anti-blocking safety performance of the entire system. The yield of the facility cucumber of the invention is higher than that of conventional planting, the environmental benefit is good, and the cost is low. The goal of maximizing biogas slurry utilization on the premise of safe utilization is realized.

Description

technical field [0001] The invention relates to a method for safely applying integrated cucumber biogas slurry with water and fertilizer. It belongs to the field of agricultural planting. Background technique [0002] Cucumber is an annual vine or climbing herbaceous plant. It has been planted since the Han Dynasty in my country and has become a common vegetable with a large planting area. Among them, greenhouse cucumber has a high yield and requires a large amount of water and fertilizer, so its irrigation is very important. [0003] In recent years, the pollution of livestock and poultry breeding has attracted widespread public attention and the governments at all levels have attached great importance to pollution control decisions. Benefits also produced a large number of by-products, namely biogas slurry. Biogas slurry is rich in elements such as nitrogen, phosphorus, and potassium. Direct discharge into the environment without subsequent treatment will have a serious...
