step four: managing a mulberry garden, wherein after mulberry seedlings are planted, ventilation and light transmission are paid attention, branches and leaves are reasonably trimmed, pinching and strip increasing are timely conducted, water draining and irrigation are paid attention, water accumulation in the garden is prevented, first fertilization is conducted when young shoots of the mulberry seedlings grow to 10cm, the first fertilization comprises a nitrogen fertilizer, a phosphate fertilizer and a potassium fertilizer, the ratio of the nitrogen fertilizer to the phosphate fertilizer to the potassium fertilizer is 8:1:1, 35kg of fertilizer is applied to each mu, the young shoots grow to 14cm, the second fertilization is an organic fertilizer, the organic fertilizer comprises 150 parts of human and animal excrement, 70 parts of rice straw, 70 parts of wormcast and 40 parts of biogas residue, the dosage is 1100kg per mu, third fertilization is conducted when the mulberry fruits are hung, the nitrogen fertilizer, the phosphate fertilizer and the potassium fertilizer are applied for the third time, the ratio of the nitrogen fertilizer to the phosphate fertilizer to the potassium fertilizer is 5:3:2, the dosage of the nitrogen fertilizer to the potassium fertilizer to the per mu is 60kg, and meanwhile intertillage and soil cultivation is conducted;

step five: the pesticide is used for preventing and treating plant diseases and insect pests, 1000 times of solution of 70% thiophanate methyl powder and 1000 times of solution of 25% triazolone wettable powder are uniformly mixed before and after mulberry blossoming and in the green fruit period, then branches, stems, leaves, fruits and the ground surface are completely sprayed for prevention, the spraying is carried out for 2 times every 8 days, 50% carbendazim wettable powder is added into soil during intertillage hilling, and the adding amount of 50% carbendazim wettable powder per mu during the intertillage hilling is 4 kg;

step six: the animal pest control method comprises the steps of feeding local chickens in a mulberry field before and after mulberry picking every year, feeding 140 local chickens in the mulberry field per mu, carrying out comprehensive disinfection treatment on the mulberry field after the local chickens are fed out of the mulberry field, feeding next batch of chicken seedlings, driving the local chickens out of the mulberry field during each intertillage fertilization, and driving the local chickens into the mulberry field 7 days after each intertillage ridging when carbendazol wettable powder is added into the intertillage ridging.

Planting 100 mulberries in the same environment by using the planting methods of the embodiments 1 to 3 respectively, namely an experimental group 1, an experimental group 2 and an experimental group 3, planting 100 mulberries in the same environment by using the traditional planting method as a control group, recording the incidence rate of plant diseases and insect pests of the mulberries in each experimental group in the growth process, and recording the quality of the mulberries in each experimental group, wherein the detection results are shown in table 1:

watch 1

Through a plurality of experiments, as shown in the table I, the occurrence rate of insect pests of the mulberry trees planted by the embodiment of the invention is far lower than that of the traditional planting method, and the single weight and the total yield of the mulberry are higher than those of the traditional planting mode, the mulberry tree seedling planting method 1 utilizes the modifying agent to modify the soil before planting the mulberry trees, the modifying agent contains decomposed farmyard manure, compound fertilizer, chitosan, 3 percent phoxim particles and mixed powder, the chitosan can inhibit various viruses, fungi, bacteria and the like in the soil, can also increase the mass propagation of bacteria, improve the beneficial granular structure of the soil, increase the content of soil microorganisms, can improve the yield of the mulberry trees, the phoxim particles can effectively prevent the generation of grubs and wireworms, the mixed powder is composed of zeolite, titanium dioxide and attapulgite of porous media, can improve the water permeability and the air permeability of the soil, the method is beneficial to the propagation of microorganisms, can improve the dispersibility of soil and increase the effects of water retention and fertilizer retention; the survival rate of the mulberry seedlings can be effectively improved by soaking the mulberry seedlings with the seedling culture solution before the mulberry seedlings are planted; 50% carbendazim wettable powder is added into soil during fertilization, intertillage and ridging, so that purple stripe disease of the mulberry can be effectively prevented, and the influence of insect pests on the mulberry can be reduced by regularly spraying a medicament; through feeding the local chicken in the mulberry field, the local chicken can eat by pests, weeds and fallen mulberry leaves and mulberry fruits in the mulberry field, so that the feeding amount of the local chicken can be reduced, the feeding cost of the local chicken is reduced, the meat quality of the local chicken fed by the mulberry leaves and the mulberry fruits is better, the pests, the weeds, the mulberry leaves and the mulberry fruits in the mulberry field can be treated, the pesticide consumption is reduced, and the situation of more pests can be prevented.
