Problems solved by technology

[0005] To solve the problem that the preventive effect of medicinal liquid on fruit tree rot disease is still poor in the prior art, the prevalence of fruit tree rot disease is still high, and the measures of scraping off the diseased spots are taken after the infection to treat the fruit tree rot disease and seriously damage the fruit trees. Hereby It is very important to develop a dry-applied preparation for the prevention and treatment of fruit tree rot and its preparation method, which has the effect of preventing and treating fruit tree rot and can provide nutrients for fruit trees.

preparation example Construction

[0041] The preparation method of the seaweed extract comprises the following steps,

[0042] Step 1, prepare solution A

[0043] Wash the dried seaweed to remove impurities, chop it into 2-3 cm and put it into a reaction kettle, add water to soak the dried seaweed, take the soaked supernatant and filter it with ion exchange resin to remove salt and heavy metals, and obtain solution A;

[0044] Step 2, prepare solution B

[0045]After putting the solution A obtained in step 1 back into the reaction kettle, add potassium oxalate, the ratio of potassium oxalate to dried seaweed in step 1 is 1:250, and after soaking and softening, an emerald green viscous liquid with a clear fragrance is obtained. The thick liquid is centrifuged to separate seaweed residue and solution B;

[0046] Step 3, prepare solution C

[0047] The seaweed residue obtained in step 2 is placed in an empty reaction kettle, and then water and potassium hydroxide are added in sequence, and then the mixed solut...

Abstract

Belonging to the technical field of trunk coating preparations for control of fruit tree rot disease, the invention relates to a trunk coating preparation for control of fruit tree rot disease and a preparation method thereof. The trunk coating preparation is mainly composed of a seaweed extract liquid, humic acid, potassium hydroxide, potassium dihydrogen phosphate, potassium sulfate, potassium nitrate and urea. The humic acid and seaweed liquid in the trunk coating preparation cooperate with each other to generate an obvious inhibiting effect on pathogenic bacteria, thus facilitating prevention and treatment of fruit tree rot disease. Also the trunk coating preparation has no need for scraping disease spots during use, and can be directly coated, avoids secondary damage to fruit tree wounds, and is beneficial to rapid repair of fruit trees. Meanwhile, the trunk coating preparation can provide nutritional ingredients to crops and automatically adjust the vegetative growth and reproductive growth of crops, thus increasing the yield of crops. The seaweed extract liquid, nitrogen, phosphorus, potassium and the like in the trunk coating preparation can provide nutritional factors beneficial to the growth and development of fruit trees to crops, and the nutritional factors can be directly absorbed and utilized by fruit trees through epidermis of fruit trees, thus being easier for the self-rehabilitation of fruit trees in the disease prevention and disease resistance process.

Description

technical field [0001] The invention relates to a dry-coated preparation for preventing and treating fruit tree rot and a preparation method thereof, belonging to the technical field of dry-coating preparations for preventing and treating fruit tree rot. Background technique [0002] Fruits produced by fruit trees have nutritional health care and medical functions. Fruits, peels, bark, and wood are also important raw materials for the food industry and chemical industry. At the same time, fruit trees have good ecological and environmental benefits, which can prevent soil erosion and increase green coverage. , Adjust the climate, thereby greening, beautifying and purifying the environment. my country is rich in fruit tree resources. Fruit trees are an important part of agriculture. Fruit tree production has strong competitiveness in the international market and is an important source of foreign exchange earnings from agricultural product exports. [0003] Rot disease, also k...
