Production management before and after sprouting of grapes

With the change of solar terms, grape plants gradually enter the period of injuring and sprouting from their dormant stages. The management of production and management of grape sprouts in spring should focus on the following points.

First, water and fertilizer management

During the germination period of grapes, a series of physiological activities such as sprouting, branching, leaf spreading, and flowering are required, and sufficient water and nutrients are required. Germination of water, depending on the soil moisture of the garden, sand or sandy loam vineyards must be filled with germination water, and other soil plants can be less irrigation. Pregerminating fertilizer is applied 1-2 weeks before the sprouting of the grapes. Generally, about 15 kilograms of urea is applied to the vine, and 10 kg of silicon-calcium-potassium-magnesium fertilizer is added at the same time. If the soil is compacted, 5 kg of eucalyptus fertiliser is added. Application method: Open the ditch on both sides of the grape, such as a ditch in the fall, this time in the grape plant.

Second, timely use of sleep bud germicide

The budding begins 20 days after the general use in Liaocheng. Lime nitrogen is usually used. Method of use: Mix lime nitrogen in a ratio of 1:6 with 70°C hot water. After the sedimentation, take the supernatant and spread the buds. Pay attention that the following 30 centimeters do not wipe, do not wipe the top buds, with the use of the same, stored in a cool dry place.

Third, do a good job of disease prevention and control

In order to reduce the number of plant diseases and insect pests in the park, before the buds inflated and no green balls appeared, the whole park thoroughly sprayed a lime sulfur agent at a concentration of 5 Baume. If the grapes had already sprouted, they could not be sprayed with lime sulfur. Now. In addition, when the young grape leaves are exposed, 80% mancozeb 800x and 10% difenoconazole 2000x can be used to control downy mildew and black pox disease; 25% of mycetophenone suspension 1500 times Control powdery mildew; 70% thiophanate-methyl WP can control botrytis at 800 times; Grape grows to 2-3 leaf-leaves; Organically managed vineyards can use Chinese herbal medicine fungicides and insecticides to prevent and treat the above diseases and insect pests.

Fourth, pruning, de-emergence, wipe bud, budding

After the European and American strains are put on shelves, the buds should be wiped. The timing of wiping buds is determined according to tree vigor. The results should be between the branches of 0.6-1 cm should be wiped early, weak buds to keep strong buds; results of more than 1 cm should be late buds, shoots in the new shoots grow to about 10 centimeters left strong buds, and In conditions that are not very dry, no watering and no fertilization, lower tree vigor consumption of nutrients to increase the rate of high fruit setting, reduce the size of the particles, can also use the fruit tree gene conditioner 500 times to adjust the tree vegetative and reproductive growth The balance between.

Isomaltooligosaccharide IMO 500

Iso-oligosaccharide uses refined corn starch as raw material, through a series of processes and gained white powder products, can promote bifidobacterium of the body significantly and have the functions of water soluble dietary fiber, low caloric value, prevent dental caries etc. , so it is a kind of functional oligosaccharide used widely.
