Greenhouse watermelon yield-increasing special fertilizer

Abstract

The invention relates to a greenhouse watermelon yield-increasing special fertilizer. In percentage by weight, the special fertilizer consists of 18 to 37 percent of soybean cake powder, 8 to 16 percent of broomcorn cake powder, 16 to 25 percent of dried sheep manure, 10 to 16 percent of soybean stem powder, 6 to 10 percent of dried chicken manure, 4 to 9 percent of white sugar, 4 to 9 percent of dried duck manure, 1 to 2 percent of rock candy, 0.5 to 1 percent of dipterex, 1 to 2 percent of superphosphate, 1 to 2 percent of grass ash and 0.5 to 1 percent of potassium sulfate. According to a proportion, all the first eight raw materials are put into a mixer together and mixed for 100 minutes before being taken out, the raw materials are then put into a grinder and ground into 200-mesh particles, the particles are taken out and then uniformly mixed with the dipterex, the superphosphate, the grass ash and the potassium sulfate, the particles are then put into the mixer again and mixed for 50 minutes before being taken out, a molding machine is used for molding the particles into a cylindrical greenhouse watermelon yield-increasing special fertilizer column which is 250g, and the yield-increasing special fertilizer column needs to be compacted and tamped and cannot be easily broken when being held by the hand.

Description

Technical field [0001] The invention relates to a special fertilizer for increasing the yield, in particular to a special fertilizer for increasing the yield of watermelon in a greenhouse. It belongs to the field of planting fertilizer technology. Background technique [0002] The main root system of watermelon has alternate leaves, deeply divided, shallowly divided and whole. The fruit has round, oval, elliptical, cylindrical, etc. The surface of the fruit is smooth or furrowed, and the epidermis is green and white, green, dark green, dark green, and black, with fine nets or bands in between. The flesh is milky white, light yellow, dark yellow, light red, scarlet and other colors. The meat is divided into tight meat and sand. The seeds are flat, ovoid or oblong, smooth or cracked. The seed coat is white, light brown, brown, black or brown, monochromatic or variegated. It is a long-day plant, likes strong light, with a light saturation point of 80,000 lux. It is suitable f...

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of: low cost, high melon fruiting rate, fast growth speed, high light receiving degree, good disease prevention performance, high-quality special fertilizer for increasing production especially suitable for growing watermelons in greenhouses, which overcomes the disadvantages contained in existing fertilizers. The nutritional content is far from meeting the nutritional needs of greenhouse watermelons. Due to the lack of nutrients, it is easy to cause the leaves of greenhouse watermelons to be yellow, small, and grow slowly. The resulting greenhouse watermelons are small, light in weight, poor in disease resistance, and prone to leaf spot disease , high fruit drop rate, more prone to defects of various diseases and insect pests
