Slow release production-increasing compound fertilizer for carrots

Abstract

The invention discloses a slow release production-increasing compound fertilizer for carrots. Raw materials comprise the following components in parts by weight: 25-30 parts of urea, 12-15 parts of a formulation containing 3-300 billion spores / gram of bacillus subtilis, 6-8 parts of a slow release treatment agent, 10-15 parts of oxytetracycline powders, 5-7 parts of fenarimol, 10-12 parts of calcium triple superphosphate, 1-3 parts of 6-benzyladenine, 6-8 parts of a potassium-enriched mixed fertilizer, 4-6 parts of attapulgite, 13-16 parts of turfy soil and 3-5 parts of a phosphorus activator. The compound fertilizer disclosed by the invention has a relatively strong killing effect on diseases of carrots. At the same time, the seed germinate rate is increased, so that carrot seedlings grow healthily and strongly. After emergence of the seedlings, the root weight, the plant height and the plant weight of the seedlings are further obviously increased. The potassium-enriched mixed fertilizer can provide comprehensive and balanced nutrients required by crops, and the fertilizer efficiency is rapid and durable, so that the fertilizer has the functions of enhancing the physiological activity and nutrition metabolism of the plant body without generating fertilizer damages, and therefore, the immunity of the plant is improved, the development of the root system is accelerated, the yield is improved and the comprehensive quality of the product is improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a slow-release carrot production-increasing compound fertilizer. Background technique [0002] Carrots are biennial herbaceous plants of the Umbelliferae family. The roots of carrots are divided into fleshy roots and absorbent roots. Its fleshy root is divided into three parts: root neck, root head (hypocotyl) and true root. The fleshy root of carrot includes secondary xylem, cambium, secondary phloem and epidermis, among which the secondary phloem is hypertrophic and developed, which is the main edible part of carrot, and most of the nutrients are stored in it. According to the length of fleshy roots, it can be divided into long root type (length greater than 20cm), medium root type (15~20cm) and short root type (6~15cm); because of different root shapes, it can be divided into conical and cylindrical. types. Carrot fleshy roots come in white, yellow, orange, red, and pu...

Problems solved by technology

However, due to the low effective utilization rate of existing compound fertilizers, rapid loss and large waste, it is impossible to completely solve the problems of soil compaction and atmospheric soil pollution of groundwater sources.

At the same time, it has few nutrients and cannot fully supply the nutrients needed for the growth and development of crops, so the growth potential is limited.

[0005] However, there is no yield-increasing agent to promote seedling germination in the existing fertilizers, which affects the normal growth of seeds after emergence, increases the probability of initial infection of diseases, and forms many unhealthy seedlings

The pretreatment of seed coating agents has achieved good results in many crops, and has obvious effects on disease prevention and yield increase. However, there are few such series of seed coating agents in existing fertilizers, and the effect of disease and insect pest control is not ideal. The current technology The measures are limited to solving the slow-release and long-term problems of fertilizers, which have a corresponding effect on improving the utilization rate of chemical fertilizers, reducing the amount of chemical fertilizers, and reducing pollution. However, the slow-release agent itself is not a nutrient element, so the fertilizer effect is not obvious

It is difficult to fully supply the nutrients needed for crop growth and development
