Special organic fertilizer for watermelons

Abstract

The invention relates to a special organic fertilizer for watermelons, which belongs to the technical field of chemical fertilizers, and is prepared from the following components in parts by weight: 20 to 30 parts of decayed stable manure, 4 to 6 parts of plant ash, 2 to 3 parts of boron zinc magnesium fertilizer, 5 to 10 parts of monoammonium phosphate, 10 to 15 parts of urea ammonium nitrate, 2 to 4 parts of sea algae extracts, 20 to 25 parts of humic acid, 10 to 15 parts of asparaginic acid, 10 to 15 parts of bean pulp, 10 to 16 parts of potassium chloride, 45 to 52 parts of bentonite, 2 to 4 parts of azospirillum brasilense, 1 to 3 parts of bacillus licheniformis, and 4 to 6 parts of EM bacteria. The special organic fertilizer for the watermelons provided by the invention is reasonable in formula, more comprehensive and balanced in nutrition, and good in use effect, the fertilizer efficiency utilization ratio and the drought resistance and the disease and insect infestation resistance can be remarkably improved, an effect on improving sierozem saline alkali soil is obvious, and the yield and the quality of the watermelons are greatly improved, so that the economic benefit of the watermelons is improved.

Description

technical field [0001] The invention relates to a special organic fertilizer for watermelons, belonging to the technical field of chemical fertilizers. Background technique [0002] Lime calcium soil is a dry soil with weak leaching in the desert steppe area of ​​the warm temperate zone. The surface layer is weakly humified, the soil organic matter content is 1-2.5%, and there are pseudomycelium-like or spot-like calcium deposits at 15-30 cm. The middle and lower parts of the profile Gypsum deposits and soluble salt deposits may also appear. The profile configuration is similar to that of brown calcic soil, but the degree of drought is slightly lower, and the leaching is slightly stronger, and the soil layer is usually deeper because of the development of sub-loess parent materials. Xinjiang and other large-area soils generally lack nitrogen fertilizers and less sulfur, and are saline-alkali lands. They are typical "lime-calcium soils", and their agricultural production and...

Problems solved by technology

[0003] The yield of Xinjiang watermelon is high, and it is sweet and delicious. In the field management of watermelon, the fertilizer applied has a great impact on the taste, quality and yield of watermelon. If the fertilizer is not balanced, it will cause the imbalance of various elements in the fertilizer, so that the To optimize the effect, it will not only lead to waste of fertilizer, but also reduce the yield of watermelon, resulting in poor economic benefits
