2022-03-25

Spring grapes are prone to sprouting untidy and flower spike degradation under early cultivation, which is not conducive to the later farming operations such as fruit preservation and fruit swelling of farmers. In view of the irregular germination of grapes in spring, the main reasons and management measures are summarized as follows:

 The main reason for the irregular germination of grapes
1. Low ground temperature in spring, abnormal climate (late spring cold, continuous high temperature) and winter freezing injury lead to poor root activity and low utilization rate of water and fertilizer.
2. The tree body is lack of nutrition. Late or no application of fruit picking fertilizer after fruit picking last year will lead to insufficient nutrient supply of the tree body.
3. spring watering improper way.
4. Soil salinization and acidification are serious, soil is too tight, and air permeability is poor.
 Measures to Promote the Germination of Grapes
1. Soil moisturizing and warming: When the ground temperature is low in spring, the sprouting water should be filled through once to avoid frequent watering with small water, keep the soil moisture at 60-70%, and use the method of furrowing, ridging and covering plastic film to moisturize and warm, and regularly rake the ground to loosen the soil to improve the soil permeability.
2. Strengthen water and fertilizer management: after grape picking, timely apply fruit picking fertilizer to supplement tree nutrition, restore tree vigor and promote grape flower bud differentiation. For orchards with insufficient nutrient reserves, apply germination fertilizer when spring buds germinate.
3. Promote root growth: in spring, when applying germination fertilizer, cooperate with "aiming at root prosperity + ruifeng guomei" to promote new roots, improve root activity, improve soil and improve root growth environment.

1. Break dormant buds: In the southern region, 2-3 weeks before germination, spray the branches wet first, and apply cyanamide or lime nitrogen and other liquid medicine evenly on the winter buds after semi-drying to break the dormant buds of grapes and promote the germination of buds.
2. Spraying and adjusting the whole plant to promote neat budding: from about 10 days before budding (bud scale expansion) to the initial stage of budding and leaf development, use Xinruifeng"Meng Enemy + Purple Qi + Treasure Flower and Treasure Fruit"Focus on spraying the fruiting mother branches, continuous use 1-2 times, each interval of 7-10 days, to promote the germination of grapes neatly, plants and inflorescence growth robust.

Precautions

1. The medicine is now prepared and used, not mixed with stone sulfur mixture and alkaline pesticide.
2. There are differences in varieties and climate in different regions. It is recommended to conduct small-area tests before popularizing them.
