| At present, China is biogas applications more countries, but also the largest producer of vegetables. Given the market demand for pollution-free vegetables and Biogas Manure increase efficiency, environmental protection and other features, this study biogas slurry as a stock solution, containing chemical fertilizers NPK mineral elements as auxiliary materials to the agricultural industry standards People’s Republic of China "water-soluble fertilizer containing humic acid NY1106-2010" implementation of the standard, developed biogas slurry foliar scientific formula. Humic acid foliar fertilization methods and resulting in greenhouse tomato, corn for the study, all treatments administered using the same amount of pre-vermicompost base fertilizer, foliar fertilizer after Topdressing slurry combination, a detailed study biogas slurry foliar fertilizer on greenhouse tomato, maize growth conditions, yields an d quality. Biogas slurry as basic research and development can be efficient, environmentally friendly and has a high market value-added liquid fertilizer products, resource utilization of biogas to provide a more effective channels. Study main conclusions are as follows:(1)biogas slurry foliar development:Biogas slurry as a pure natural liquid fertilizer type, which also contains a variety of nutrients for plants, such as soluble inorganic salts(Available NPK mineral elements), 17 kinds of amino acids, plant growth regulators, enzymes Multiple classes and organic acid and humic acid, etc., with easily absorbed by crops, pest prevention reasons and because humic acid rich functional group has a higher mineral elements carrying capacity and other characteristics. Based on these advantages, the addition of mi neral nutrients, and related ingredients, materials, etc., and adjust the p H finally prepared slurry foliar fertilizer. Physical and chemical properties of the slurry for foliar: a large number of elements(with N, P2O5, K2 O dollars) the total amount of 302.3 g / L, its nutrient content ratio of N: P 2O5: K2 O = 11: 9.47: 10.7, PH = 7.08 the color is dark, its stable temperature range of 4 ℃ ~ 38 ℃;(2)the combined effects of greenhouse tomato: Under basal fertilizer and other farming operations are the same conditions in the growth of tomato late(the first spike fruit enlargement), biogas slurry foliar application on growth of greenhouse tomato plants significantly wherein biogas slurry foliar AC2 influence the formulation of greenhouse tomato plants grown extremely significant; different humic acid foliar spraying at late growth stage compared to no fertilizer on greenhouse tomato yield was more significant. Treatment compared with CK, AC1, SUNNY, AC2 respectively yield 11.19%, 20.84%, 37.59%; fruit quality, the test measured each of the first and third ear ear fruit fruits treated group compared to the no foliar spraying fertilizer treatments CK,(AC1, SUNNY, AC2) treatment group, the first spike fruit vitamin C content of fruit with a third ear, total sugar content were significantly improved, the most prominent of which deal with AC2, vitamin C content The total sugar content were increased by 27.20% compared to CK, compared with 40.35%. Foliar spraying each processing a small amount compared to CK accumul ation, are within 19.50 mg ~ 20.50 mg / kg range, well below the 440 mg / kg of nitrate content of its national limits.(3)combined effects of corn:In the basal fertilizer and other farming operations are the same conditions as in the maize growing late(early jointing) Spraying Biogas Slurry Foliar Fertilizer on Maize Yield nutritional factors significantly. CK were significantly improved compared to AC1, SUNNY, AC2 treated ear length, rows per ear, kernels per row, kernel weight and other indicators; Yield AC1, SUNNY, AC2 treated compared to CK respectively increase 10.51%, 12.35% 15.91%; in terms of the quality of maize grain, AC1, SUNNY, AC2 treatment compared to CK, its fat content, protein content were significantly improved. |
