Is there a patent for the modular plastic planting box?

Symptoms of stem rot: it is called neck rot. The stems and leaves turn yellow from the lower part of the stem and the leaf edge of ginger, and then spread to the whole ginger, and soon the ginger plant will die. 2. Rot from the outside to the inside. 3. There will be water stains on the stems of ginger stalks. Symptoms of rotten ginger stalks:? The infected ginger slices are yellow-brown in water and gradually soften and rot inside. When ginger is dug out and squeezed by hand, it will squeeze out white juice and have a bad smell. Rot is controlled by agriculture spreading from the inside to the outside at the base of ginger stem. Select disease-free ginger varieties. When sowing, the ginger seeds should be disinfected, and the cut ginger should be soaked in 800 times solution of 50% carbendazim wettable powder for 5-8 hours, or in 2000 times solution of neophytomycin for 24 hours. Ginger fields have been selected and disinfected.

Crop rotation. Continuous cropping for many years is one of the main causes of serious stem rot. Continuous cropping for many years will cause bacteria to accumulate in the field, and once they encounter suitable climatic conditions, bacteria will be infected with diseases. Ginger can be mixed with Gramineae for 2-3 years. Disinfecting the soil with chloropicrin and weibaimu before planting can effectively kill harmful bacteria and beneficial bacteria in the soil, so the beneficial bacteria must be supplemented after treatment. Before arable land, the diseased plants with gray mold and Sclerotinia sclerotiorum and their residues, even the topsoil of the diseased plants left by the previous crop in the arable land soil, should be thoroughly removed from the field and treated centrally. Mix the fine soil with about 4 kg of 80% carbendazim per mu, and spread it into the cultivated soil evenly. Soil treatment: Ginger is an easily replanted crop with obvious autotoxicity. Therefore, it is very important to treat the soil before planting ginger. Soil fungicides such as lime nitrogen and cotton. Can be used for soil disinfection, and should be watered once before planting. Invented the patented product of Kejunling, which is a non-toxic, harmless and residue-free biological preparation. By killing and antagonizing the pathogenic bacteria of stem-base rot and releasing beneficial bacteria, the stem-base rot of ginger is treated with obvious effect, which can cure the ginger that has suffered from stem-base rot.
