Embodiment 1

[0036] Take 1000 grams of fresh kelp as the raw material, shred it mechanically; add 40 grams of potassium carbonate, add water to make the final concentration 2wt%, stir once every half hour, and treat for 2 hours; then filter and collect the filtrate. Dip the filtrate with an industrial brush and paint evenly on the whole trunk and branches, and then spray 3wt% calcium chloride aqueous solution to make it solidify, so as to form a biological protective film on the fruit tree branches.

[0037] The protective film formed by the method has the function of water retention, can prevent the branches and trunks from evaporating water, and can effectively prevent germ spores and pest eggs from germination directly on the branches and trunks of trees, thereby blocking the spread of diseases and insect pests. Tests have proved that it can reduce the population density of red spider mites, the control effect is 55% compared with 85% with treatment, and the prevention effect is increase...

Embodiment 2

[0039] Before the new shoots germinate in spring, the trees are sprayed with 1% copper sulfate concentration. Then take 100 grams of dried kelp as raw material, add 5 times of water to soak for 10 hours, mechanically shred, add 30 grams of potassium carbonate, add water to make the final concentration 3wt%, stir once every half hour, and process for 2 hours; then filter , collect the filtrate, dip the filtrate with an industrial brush to evenly brush the whole trunk and branches, and then spray 5wt% calcium chloride aqueous solution all over the body to make it solidify, so as to form a biological protective film on the fruit tree branches.

[0040] The protective film formed by the method can prolong the medicinal effect of copper sulfate, prevent and treat trunk ring disease in a targeted manner, eliminate overwintering spores, reduce fruit ring disease and improve the control effect of anthracnose. Tests have shown that it can reduce the population density of the first gene...

Embodiment 3

[0042] Before new shoots germinate in spring, the tree body is sprayed with 5B lime sulfur mixture. Then take 200 grams of dried kelp as raw material, add 5 times of water to soak for 10 hours, mechanically shred, add 40 grams of potassium carbonate to make the final concentration 4wt%, stir once every half hour, and process for 2 hours; then filter, Collect the filtrate, dip the filtrate with an industrial brush and evenly brush the whole trunk and branches, and then spray 5wt% calcium chloride aqueous solution all over the body to make it solidify, so as to form a biological protective film on the fruit tree branches.

[0043] The protective film formed by the method can prolong the medicinal effect of the lime sulfur mixture, kill the overwintering mite pests, and reduce the incidence base. Tests have shown that it can reduce the population density of the first generation of spider mite, increase the control effect by 55%, and increase the control effect of dry rot and rotu...

Abstract

The invention relates to a method for preventing and curing plant diseases and insect pests of fruit tree branches. The method is characterized by comprising the following steps: firstly, smashing fresh kelp directly or adding water with a mass ratio of 5-9 times after smashing dry kelp, adding alkaline substances, carrying out stirring, enabling the final mass percentage concentration of the alkaline substances to be 2-5%, and carrying out stirring every half hour, wherein the processing time is 1-2 hours; carrying out filtering, evenly coating the fruit tree branches with filtrate through a hairbrush, and evenly spraying a calcium chloride aqueous solution with the mass percent being 2-5% to the coated parts, thereby forming biological protective films on the fruit tree branches. By means of the method, a good preventing and curing effect for apple dry rot, ring rot and kanazawa spider mites is achieved. Killing insecticide is added in the processing of coating the protective films, rainwater is prevented from washing the insecticide, the retention tine of the insecticide on the fruit tree branches is prolonged, and the preventing and curing effect is more obvious. According to the method, scraps of the kelp can serve as raw materials, waste is turned into wealth, and the environmental protection effect is obvious.

Description

technical field [0001] The invention relates to a method for protecting fruit tree branches from infestation by diseases and insect pests and enhancing the effect of preventing and controlling fruit tree branches and diseases and insect pests, belonging to the field of fruit tree disease and insect pest control. Background technique [0002] At present, Shandong Province alone has nearly 10 million mu of fruit planting area, including more than 5 million mu of apples. Apple branches are easily infected and harmed by diseases and insect pests. The most harmful diseases and insect pests include ring spot, rot, dry rot, long beetle and jerky beetle. Mature fruit trees use more than 2 kilograms of chemical pesticides per mu per year for pest control. These measures not only increase the cost of planting fruit trees, but more seriously, the pesticide residues left on the surface of the fruit and in the soil washed by rainwater have a negative impact on There are great risks to h...
