The new tricks of fertilizing and controlling insects in autumn mulberry gardens are as follows:
In order to promote the growth of mulberry and improve the quality of mulberry leaves, the feeding amount of mid-late autumn silkworms and the spring mulberry leaf production in the next year, the management measures such as fertilization and pest control in autumn mulberry gardens are crucial.
Fertilize. After the start of the silkworm period, the back of the mulberry leaves was sprayed once with urea, potassium dihydrogen phosphate or the like to improve the quality of the autumn leaves and increase the yield of the mulberry leaves. Strictly control the concentration of fertilizer solution, and mix the two fertilizers with photosynthetic nutrient film fertilizer to help plants absorb a lot of light fertilizer, light energy, light, compatible with conventional fertilizers and nutrients to supply plant growth and development to the limit. If the autumn is less rainy and the soil is dry, it should be properly watered and shallowed once to reduce the amount of grass in the spring.
Treating insects. Focus on the prevention and control of mulberry mosquitoes. In the early stage of the disease, the targeted medicinal mulberry spray should be used in time. When spraying, it must be used together with the new high-fat membrane to improve the utilization rate of the active ingredients of pesticides. The high-toxic pesticides can be modified to be poisoned, and the poisoned pesticides are low-toxic and low-toxic. The pesticide is slightly toxic. Control the volatile and volatile pesticides, prevent the rainwater from scouring, reduce the dosage per acre (half), and improve the control effect (multiple times).
