Nanometer composite fertilizer for relieving vegetable magnesium deficiency

Abstract

The invention discloses a preparation method of nanometer composite fertilizer for relieving vegetable magnesium deficiency. The preparation method comprises raw material preparation, urea solution preparation, filtrate preparation, and nanometer raw material and nanometer composite fertilizer preparation. The nanometer composite fertilizer replaces the daily fertilizer so that a seeding ratio is increased and magnesium absorption of vegetables is promoted. In capsicum, kidney bean and leaf vegetable plantation, the nanometer composite fertilizer can produce obvious effects of relieving magnesium deficiency. Blumea balsamifera powder is subjected to nanometer treatment so that a disease infection and insect pest ratio is reduced after Blumea balsamifera absorption by vegetables. The nanometer composite fertilizer can be flexibly used and improve a yield by about 8.2%. The preparation method can improve composite fertilizer effective component absorption of vegetables and reduce fertilizer waste.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a nano compound fertilizer used for magnesium deficiency of vegetables. Background technique [0002] During the growth of vegetables, magnesium plays an important role in the synthesis of chlorophyll and photosynthesis. In addition, magnesium is also related to the synthesis of proteins, and can activate enzymes that promote reactions in plants. If vegetables lack magnesium, it may cause Premature senescence and shedding of leaves, and even necrosis of the entire leaf will seriously affect the quality of vegetables. Magnesium-deficient plants are often relatively short and grow slowly, especially in the fruiting period. With the increase of fruits, the phenomenon of magnesium deficiency will become more serious. Lead to low vegetable yield, poor quality, and small fruits. [0003] The main reasons for its magnesium deficiency are as follows: In some ar...

[0002] During the growth of vegetables, magnesium plays an important role in the synthesis of chlorophyll and photosynthesis. In addition, magnesium is also related to the synthesis of proteins, and can activate enzymes that promote reactions in plants. If vegetables lack magnesium, it may cause Premature senescence and shedding of leaves, and even necrosis of the entire leaf will seriously affect the quality of vegetables. Magnesium-deficient plants are often relatively short and grow slowly, especially in the fruiting period. With the increase of fruits, the phenomenon of magnesium deficiency will become more serious. Resulting in low vegetable yield, poor quality and small fruit

[0003] The main reasons for its magnesium deficiency are as follows: In some areas, due to the influence of the regional natural environment, the soil magnesium supply will be insufficient, or too dry and strong light will lead to the loss of magnesium. Now usually when magnesium deficiency is found, Magnesium sulfate solution is usually sprayed to achieve the effect, but if the concentration of potassium in the soil is too high, it will affect the absorption of magnesium, and the lack of phosphorus will also cause insufficient absorption of magnesium, so spraying with magnesium sulfate alone may cause waste waste and drug residues Pollution of the environment is more likely to have adverse effects. Therefore, a nano-composite fertilizer specially used for vegetable magnesium deficiency should be invented to regulate and improve the content of related components in the vegetable growth environment so that it can effectively absorb
