The biogas slurry is fully fermented, which is rich in nutrients required by various crops, so it is very suitable for external fertilization, and its effect is better than that of fertilizer. Crops and fruit trees can enter the flowering stage, booting stage, filling stage and fruit expansion stage to carry out bio-liquid spray fertilizer, which is beneficial to flower bud differentiation, flower-preserving and fruit-preserving, and has obvious effect of increasing yield, and fruit weight gain is fast and good quality. The relevant practical technologies are introduced as follows for reference in farmers' production:
First, technical points:
1. Biogas slurry: Biogas tanks collected from normal gas production for more than one month, clarified, gauze filtered to prevent clogging of the sprayer.
2. Fertilization period: the germination stage of the crop (the tillering stage), the flowering stage (the booting stage, the beginning fruit stage), the fruit expansion period (the filling stage), and the outbreak period of the pests and diseases. Spray once every 7-10 days.
3, fertilization time: morning dew after drying (about 10:00), summer evening is appropriate, no heat before noon and heavy rain before the rain.
4. Concentration: According to the concentration of biogas slurry, crops, seasons and temperature, the general principles are: seedlings, young leaves, 1 part of biogas slurry plus 1-2 parts of water; summer high temperature, 1 part of biogas slurry plus 1 part of water When the temperature is low and the old leaves are old, there is no need to add water.
5, dosage: depending on the variety and growth of crops, generally 40-100 kg per 667 square meters.
6, can be applied alone, or with fertilizer, pesticides, growth regulators and other mixed application. Spraying is mainly applied to the back of the leaf to facilitate crop absorption.
Second, the application method 1, biogas spray fruit tree: from the beginning of the flowering period, combined with the flower and fruit, 7-10 days, until the leaves before the fall. 1 part of biogas slurry plus 1 part of clear water, the effect: preserved flowers and preserve fruit, promote the same fruit size, good gloss and consistent maturity. After fruit picking, it can also adhere to 3-4 times, which is conducive to flower bud differentiation and enhance the cold resistance of trees.
2, biogas spray mushroom; after the mushrooming, 500 grams per square meter, biogas slurry plus 1-2 times water, spray once a day, improve mushroom quality, increase production, increase production range of 37% -140%.
3, spraying the watermelon with biogas slurry: starting from the beginning of the vine, adding 10 kg of clear water to each 10 kg of biogas slurry; in the initial fruit period, adding 30 kg of clean water per 15 kg of biogas slurry; 20 kg of biogas slurry plus 20 kg of water in the later stage. By spraying, it can increase the disease resistance, increase the yield, and there is a place with blight, and the effect is more remarkable.
4. Spraying grapes on the biogas slurry: the leaf-expanding period begins, and ends before the leaves, 7-10 days. The ratio of biogas slurry to water is 1:1. Effect: The fruit is swollen and consistent, which can increase the yield by about 10%, and treat both diseases and insect pests.
