Vineyard Management Method in May

The beginning of May is the new shoot growth period and the blooming period of the vine, and management should be done well. Only with good management can the yield of grapes have a good result. Here is an introduction to the vineyard management methods in May.

Vineyard management methods in May, wiping buds and fixing shoots

Attention should be paid to sparse buds, weak buds and over-dense buds with improper growing parts, so that the tree sprouting strong and in a proper position.

Tie up new shoots

In the process of fixing the shoots, the new shoots that have been fixed should be tied every 15 cm to ensure that the branches are distributed reasonably. In the process of tying, it is necessary to use the softness of the branches and vines to put it on the shelves evenly, pay attention to the slope of the shelves not to be too large, and do not go too far in the transition from the stand to the horizontal frame.

New shoot topping

In the process of grape vine topping, the time for topping varies depending on the strain. Among them, Kyoho vines that are prone to falling flowers should be topped on all new shoots 3 days before flowering, and varieties with relatively easy fruit setting such as Red Globe should be topped after flowering. Topping it in about 3 days. The tendrils are removed at any time throughout the growth period.

Topdressing fertilizer before flower

In terms of fertilization, 10 days before flowering, between rows on the other side of the trunk where sprouting fertilizer is applied, at a distance of 0.5 to 0.6 meters from the trunk, a 10 cm deep furrow is required to apply the pre-flowering fertilizer. Apply 25-50 kilograms of diammonium phosphate, 25-50 kilograms of potassium sulfate, and 2-5 kilograms of medium and trace element fertilizers per mu. Mix the fertilizer and apply it, bury the soil, and water it once. Spraying 0.3% urea + 0.3% potassium dihydrogen phosphate + 0.1% borax or medium and trace element fertilizer (calcium magnesium boron zinc iron) solution 1 to 2 times on the leaves before flowering can promote pollination and fertilization.

Thinning spikes

In the process of thinning flower ears, the fruit grower must thin out the small flower ears and cut off the side ears. About 5 days before flowering, cut 1/5 to 1/3 of the tip of the inflorescence, and thin out the excessive inflorescence. The strong branch retains 1 ear of fruit, the weak branch does not retain fruit.

Cultivator weeding

To remove the weeds in the vineyard, loose the topsoil on the border surface, cover the border surface with grass, and arrange the drainage ditches to prevent water accumulation.

Pest control In terms of pest control, fruit growers should pay attention to spraying 3000 times 2.5% deltamethrin EC and 1500 times 10% imidacloprid to prevent and control A. lucorum and aphids in the early stage of vine germination. Use 500 times carbendazim or 500 times dysenzine before flowering to prevent black pox, powdery mildew, downy mildew, etc., spray once every 10 to 15 days, and pay attention to timely respray after rain.

The grape should be sprayed three times during the flowering period. Grape management has entered a critical period in May, and the medicine must be sprayed three times in time. Focus on three key control periods: the inflorescence exposing period, the inflorescence separation period, and the 2 to 4 days before flowering.

Inflorescence display period:

The focus of prevention and treatment is A. lucorum, leafhoppers, and black pox. The prevention method is based on: 300 kg of water + 1 bottle of white Tyrone + 2 bags of Qianhong + Beibo? 1 bottle of flusilazole + 1 bottle of brassin + 20 grams of Albit.

Inflorescence separation period:

The focus of prevention and control is gray mold and cob brown blight. It is also an important period for boron and zinc supplementation to prevent large and small grains, no caps, and tight inflorescences. At the same time, it is also necessary to treat insect pests such as wax cicada and lucorum. Prevention method: 300 kg of water + 1 bottle of pyraclostrobin + 70% azoxybacter? 1 bag of Procymidone + 2 bags of 10% Difenoconazole + 1 bottle of Jinzhengshuai + 1 bottle of Zhengmeng + 1 bottle of Super 501 or Hongrui amino acid 2 kg + Albit 20 grams.

2 to 4 days before flowering:

The control point is the same as the inflorescence separation period. Prevention and treatment method: 300 kg of water + half a bag of 70% Propisenzine + 1 bottle of Aike + 3 bags of 10% difenoconazole + 1 bottle of positive meng + 1 bag of oligosaccharide boron + 20 grams of Albit.
