Special fertilizer for dragon fruits

Abstract

The invention discloses a special fertilizer for dragon fruits. The special fertilizer is prepared from, by weight, 35-40 parts of cow dung, 20-24 parts of fresh grass powder, 28-34 parts of straw, 18-23 parts of charcoal powder, 10-14 parts of plant ash, 7-11 parts of vinasse, 1-5 parts of plant hormones, 10-15 parts of kieselguhr, 2-6 parts of castor-oil plants, 5-9 parts of EM biologic bacterium agent, 1-5 parts of cyclohexanol acetic acid ester, 1-5 parts of zinc sulfate, 1-5 parts of ammonium chloride, 2-6 parts of ferrous sulfate, 2-6 parts of potassium humate, 5-9 parts of garlic, 6-10parts of pyrethrum, 4-8 parts of fructus cnidii and 5-9 parts of rhizoma polygonati. The ferrous sulfate and the plant hormones in the fertilizer are subjected to resin coating, iron can be slowly released in soil to avoid that releasing a large amount of iron at a time causes pressure on the environment, available iron can be protected from being converted into non-effective iron which plants cannot absorb and utilize, the plant hormones can promote new root emerging of the dragon fruits, the iron absorbing rate of emerging root tips is greater than that of old roots, and it can be avoided that the iron deficiency phenomenon in the growth process of the dragon fruits occurs.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for dragon fruit and a preparation method thereof. Background technique [0002] Dragon fruit (Latin name: Hylocereus undulatus Britt), also known as red dragon fruit, dragon fruit, fairy honey fruit, jade dragon fruit. Cactaceae, the genus Tianchi. The fruit is oval, 10-12 cm in diameter, red or yellow in appearance, with green rounded triangular fronds, white, red or yellow pulp, and fruit with black seeds. The common disease of dragon fruit in the planting process is iron deficiency. Iron deficiency will cause erythema and yellowing on the stems and leaves of dragon fruit, which will affect photosynthesis and lead to a decrease in yield. The current solution is to yellow the stems and leaves of pitaya When spraying ferrous sulfate solution or adding ferrous sulfate directly to the fertilizer, ferrous sulfate directly sprayed on the surface of dragon ...

Problems solved by technology

The common disease of dragon fruit in the planting process is iron deficiency. Iron deficiency will cause erythema and yellowing on the stems and leaves of dragon fruit, which will affect photosynthesis and lead to a decrease in yield. The current solution is to yellow the stems and leaves of pitaya When spraying ferrous sulfate solution or adding ferrous sulfate directly to the fertilizer, ferrous sulfate directly sprayed on the surface of dragon fruit will cause pesticide pollution, and due to the complexity of the soil environment, the ferrous sulfate directly added to the fertilizer is easy to transform It is ineffective iron, and its aftereffect is weak. At this stage, there is a lack of fertilizers specifically for dragon fruit cultivation
