Novel compound fertilizer capable of increasing leaf lettuce yield

Abstract

The invention discloses a novel compound fertilizer capable of increasing a leaf lettuce yield. The novel compound fertilizer comprises the following components in parts by weight: 29-35 parts of corn stalks, 18-20 parts of soybean meal, 25-30 parts of rape seed cake powder, 12-15 parts of corn cob powder, 4-5 parts of actinomycetes and 3-4 parts of photosynthetic bacteria. The novel compound fertilizer contains a great amount of organic fertilizers, is added with a beneficial microbial flora, balanced and rich in nutrient, not only capable of increasing the yield of the lettuces and improving the quality of lettuces, but also capable of activating soil, improving the resistance of the leaf lettuces, reducing the diseases, and is green, efficient and environment-friendly.

Description

technical field [0001] The invention relates to a chemical fertilizer, in particular to a compound fertilizer capable of increasing the yield of lettuce, and belongs to the technical field of planting fertilizers. Background technique [0002] Lettuce, also known as naked oats, is also called bitter vegetables in some places. It belongs to chrysanthemum. It is a sharp-leaved lettuce with young shoots and leaves as its products. The leaves are long lanceolate, light green in color and crisp in texture. Tender, extremely tender, fragrant, with a unique flavor, contains a lot of vitamins and nutrients such as calcium, iron, protein, fat, vitamin A, vitamin B1, vitamin B2, etc. It is the top grade among raw vegetables, known as "phoenix tail" say.

[0003] The application number is 201210085815.5, the application date is 2012.03.28, and the name is "a compound fertilizer for promoting the production increase of lettuce". A preparation method of a compound fertilizer for promoting the production increase of lettuce is disclosed, which is composed of the following raw materials: urea 15- 19%, monoammonium phosphate 2-4%, potassium sulfate 4-6%, potassium dihydrogen phosphate 4-7%, etc., when fertilizing, the nutrient fertilizer of the present invention is compared with the compound fertilizer commonly used in the gardening field, and the planting areas are randomly set , each fertilizer adopts one-time input, adopts the same field management measures, after the compound fertilizer of the present invention is applied statistically, the lettuce can be increased in income and the disease can be reduced, but the present invention uses inorganic chemical fertilizers entirely, and the ecological benefit is reduced, which is not conducive to sustainable ecological planting

[0004] The application number is 201010204446.8, the application date is 2010.06.14, and the name is "a method for configuring lettuce-increasing fertilizer", which discloses a method for preparing lettuce-increasing fertilizer, which is composed of: dried manure, rapeseed cake powder, buckwheat Shell powder, sorghum cake powder, soybean pod powder, corncob powder, licorice powder, carrot leaf powder, pine needle powder, datura powder, a large amount of organic fertilizer produced in the ingredients can meet the growth needs of lettuce, grow The lettuce is large in size and sufficient in weight, which not only increases the yield but also effectively overcomes the defects of yellow leaves and slow growth of the lettuce caused by the lack of nutrition in the existing fertilizers. However, the invention uses organic fertilizers, and the active ingredients It is difficult to control, and the effect is not uniform and stable enough, so it is not easy to promote and use on a large scale
