A kind of correction method of citrus boron poisoning

Abstract

The invention discloses a correction method for citrus boron poisoning, which adopts a preparation for the underground part and a preparation for the above-ground part; the preparation for the underground part is 15% copper ammonia and algal seaweed fertilizer; the preparation for the above-ground part is 25% pyrazole Ayresstrobin, amino acid calcium, and sodium nitrophenolate; the corrective method is: after the diagnosis of citrus boron poisoning, spray the crown of the tree 4 times on the ground part according to the reagent ratio, once a month, and the leaves must be sprayed thoroughly each time; at the same time, The underground part is irrigated 3 times according to the reagent ratio, once every 20 days or so, and the ratio solution is 10-15kg each time. After the diagnosis of citrus tree boron poisoning, adopt the optimal ratio of the present invention, the yellowing area of ​​citrus tree leaves will not expand, the leaves will not fall off, and the new shoots drawn out after 2 months will be normal, and the leaves and soil will be normal within 6 months The effective boron value is normal, and the impact on the yield of the tree in the current year is relatively small; at the same time, the technology adopted in the invention has strong practical operability, quick effect, and low cost to solve the boron poisoning of citrus.

Description

Technical field[0001]The present invention relates to a formulation and method of use using a citrus boron poison.Background technique[0002]Citrus is one of my country's dominant agricultural products in national planning. In 2018, my country's citrus area and production were ranked first in the world, with more than 40,000 mu of planting, 39 million tons of production, and citrus has become one of the main pillar industries of China's South Agriculture.[0003]There are more than 19 provinces of citrus planting citrus, including citrus, cultivation of citrus in Guangxi, Hunan, Jiangxi, Guangdong, Yunnan, mostly red soil and yellow. Red and yellow soil land, in addition to lack of nitrogen, phosphorus, calcium, magnesium and other nutrients such as nitrogen, phosphorus, calcium and magnesium, etc., and is generally deficient in boron. The lack of boron is not only manifested in my country's red and yellow soil citrus planting area, and there is also a non-red, and the citrus planting ...

Problems solved by technology

After boron poisoning in citrus, a large amount of irrigation, application of nitrogen and phosphorus fertilizers after short pruning, and additional application of lime are used to correct the damage caused by boron poisoning to citrus trees. None of the above methods can effectively correct the problem of boron poisoning in citrus trees.

[0008] At present, after excessive boron is applied to citrus trees, before the citrus trees absorb a large amount of boron, a large amount of water is poured on the poisoned trees, and the applied boron is washed and leached with a large amount of water to reduce the damage of boron to citrus trees. There are effective methods, but this method requires technical personnel with experience in boron poisoning management to detect and diagnose boron poisoning in time. Once obvious symptoms appear after absorption, it is difficult to solve it by irrigation. Water can flush the excessive boron out of the citrus orchard, but it is difficult to effectively implement the method of flushing with water. First, it is difficult for many non-professional technicians to identify it in time; second, many citrus orchards do not have So many water sources can be used for irrigation. Third, it is difficult to wash away the boron in the soil through the amount of irrigation water. Instead, the boron in the soil is washed from one citrus orchard to another, even due to the leaching of water. Solubilization, water brings boron from the surface of the soil to the deeper soil layer, making it difficult to really solve the problem of boron poisoning

[0009] By applying lime to the soil, in theory, the calcium in the lime can combine with boron to form a precipitate to reduce the damage of boron to the tree, but this method requires a large amount of lime, and the lime is generally scattered on the surface of the soil. Calcium in the soil is also easily fixed and cannot be effectively absorbed, resulting in ineffective effects. Moreover, applying lime in some alkaline soils will aggravate the alkalinity of the soil, which is not conducive to the growth and results of citrus trees.

[0010] The effect of applying nitrogen and phosphorus fertilizers after cutting the branches of the poisoned tree is very slow, and some trees may die before returning to normal. Moreover, if the branches are cut short during the high temperature period, the damaged branches will be accelerated. dry up and die
