After the grape is picked, the vine has a growing period. If it can strengthen the management, it can not only enhance the ability of the tree to store nutrients, but also improve the wintering resistance of the plants. It is the guarantee for high yield and stable production in the next year.
First, the application of post-harvest fertilizer Linyi fertilizer network copyright
After the fruit is harvested, depending on the growth of the plant, about 12 kg of quick-acting nitrogen fertilizer is applied per mu, and 0.3% urea solution is sprayed 2-3 times to promote the normal growth of the tree potential. If the tree grows vigorously, it should be applied less to prevent the new shoots from growing. The autumn application of the base fertilizer is completed from late September to early November. Use the ditch fertilization method. Linyi Fertilizer Network Copyright
Second, loose soil anti-staining and drought-proof Linyi Fertilizer Network Copyright
In summer and autumn, the orchard is prone to weeds. After harvesting, it is necessary to timely cultivate and weed, and at the same time, deep-cut. From August to October, grapes often face the threat of autumn drought. Therefore, it is necessary to pay attention to drought-resistant irrigation. If there are consecutive sunny days for 15-20 days, they should be irrigated in time to maintain the field water holding capacity of not less than 60%. Linyi Fertilizer Network Copyright
Third, the prevention and control of pests and diseases Linyi Fertilizer Network Copyright
The main diseases of grapes are downy mildew, black pox, rust and so on. August-September is the epidemic period of downy mildew, especially in rainy years. After grape harvesting, it is still necessary to continue to control the disease. You can use "new high-fat film" + fungicide + insecticide to control, " The new high-fat film can enhance the effect of the drug, no damage to the tree, neutral, and can be mixed with any agent. In addition, attention should be paid to the control of pests such as chafers, grape hawk moths, and two-star spider mites. Linyi Fertilizer Network Copyright

After picking the fruit, the weeds in the garden should be removed, and the cut diseased shoots, diseased leaves, diseased fruits, dead branches and sundries will be taken out of the garden to be buried or burned to reduce the source of pests and diseases, and then the whole garden will be sprayed. Tree General" disinfection. Linyi Fertilizer Network Copyright

H135
A type CPE performance
Mainly used as the impact resistant modifier of PVC. At present, it takes 95%
share of the impact resistant modifier market of domestic PVC. The additive
shares of H135 A type CPE as the impact resistant modifier of PVC profile
shapes is 9~ 12; the shares as the impact resistant modifier of PVC water
feeding pipe and other liquid transfer pipe under pressure is 4~ 6; this can
effectively improve the low temperature resistant impact property of PVC
product. In addition, H135A type CPE is widely added into the products including
PVC plate, sheet, calcium-plastic box, case of household appliances and
electrical appliance fittings to improve the mechanical property and electrical
property.
H135 A type CPE can be compatible and use with most plastics and rubbers
simultaneously. The polymer cross blend system with bad compatibility can take
CPE as bulk filler. The rubbers used together with CPE include caoutchouc,
butadiene styrene rubber, ethylene propylene diene copolymer, polyurethane
rubber, acrylonitrile butadiene rubber, neoprene and chlorosulfonated
polyethylene etc. The plastics used together with CPE include PVC, PE, PP, EVA
and PA etc, which greatly improve the low temperature resistant impact property
and increase flame resistance, oil and aging resistance, corrosion resistance
and insulatibity. This can make the plastic product have high filling property
and reduce production cost.
Packing and Storage :
PP bags with PE film
inside, Net Weight of 25 ± 0.2kg per bag ; as the viscoelastic and water
absorption of CPE resin are strong, this product shall be stored in the dry and
ventilated warehouse with stack height no more than 10 bags and avoid
solarization, damp and takes strict precautions again stress. It is not
dangerous cargo.
