How to fertilize the vineyard management skills in the early winter makes the grapes grow better in the coming year. There are a lot of wintering pests in the ground leaves and weeds. Some fruit farmers do not seriously or even clean the orchards after autumn, which makes the grape pests in the coming year serious or difficult to control. First, after the leaves of the grapes are clean, the dead branches, fallen leaves, weeds, etc. should be thoroughly cleaned out of the orchard; Secondly, the branches under the grape trimming in the spring of the next year, especially the diseased branches, and the old skin should be cleaned up in time, and the cleaned out debris should be buried or incinerated (don't just throw it away and stack it). This is an effective way to prevent the spread of pests and diseases and to control and reduce the occurrence of pests and diseases. Use of Bordeaux liquid and stone sulphur mixture. Decades of practice have proven that Bordeaux mixture and stone sulphur mixture have low cost, low effect, low residue and no drug resistance. In particular, Bordeaux fluid is better for grapes than other fruit trees. The specific method is: before germination, when the scales of the grape winter buds begin to burst, spray a concentration of 3 to 5 waves of sulphur sulphur mixture, spray the branches, the ground, the pillars and the iron wire all the time when spraying; One time 1:0.5:240 times Bordeaux mixture; after the flowering period, spray 1:0.7:200 times Bordeaux mixture; coloring period 1:0.7:180 times Bordeaux mixture; grape 1:1:180 times before harvesting Bordeaux mixture. Application of nitrogen, phosphorus and potassium fertilizers. The specific fertilization method is: the first fertilization before the germination of the grapes or before the flowering, at this time mainly using nitrogen fertilizer, before the flowering, 3 to 5% of the superphosphate infusion solution can be used for root dressing to increase the fruit setting rate. In the early stage of the growth of young fruit, the second fertilization is still based on nitrogen fertilizer, and the appropriate amount of phosphorus and potassium fertilizer is applied. For the third time, phosphorus and potassium fertilizers were applied before and during ripening of berries to improve fruit quality and promote shoot maturity. In addition, supplementation of nitrogen fertilizer after grape harvesting can enhance the photosynthesis of the leaves and increase the nutrient storage in the branches. However, if the application is too much or too late, it will easily cause plant greed and reduce cold resistance. Most of the phosphate fertilizer is mixed with organic fertilizer and applied in the autumn. Regardless of the method used when fertilizing, the principle of less root injury is adopted.
