From the beginning of April to the beginning of May, it is the new shoot growth period and the flowering period of the vine. In the interviews at the grassroots level, the reporter found that some fruit farmers are very blind in scientific management of the vineyard at this stage. In this regard, Zhang Zongqin, an associate professor at the College of Forestry, Northwest A&F University, gave scientific guidance to the majority of fruit farmers. In the process of tying the new shoots, the new shoots that have been fixed should be bound every 15 cm to make the branches distributed reasonably. In the process of binding, it is necessary to put the branches on the softness of the branches and make them evenly distributed. Pay attention to the slope of the upper frame and not the slope, and the transition from the stand to the horizontal frame should not be bent. In addition to the new shoots, in the process of picking the vines, the strains are different, and the time of picking the heart is different. Among them, the vines that are easy to fall are plucked to all the new shoots 3 days before the flower, and the red earth is relatively easy to sit on the fruit. The variety should be topped about 3 days after flowering. The tendrils are removed at any time throughout the growing season. In the application of fertilizer before the flowering, Zhang Zongqin said that in the 10 days before the flower, on the other side of the trunk of the sprouting fertilizer, 0.5 to 0.6 meters from the trunk, open a 10 cm deep ditch to apply the pre-flower fertilizer. Apply 25 to 50 kg of diammonium phosphate per acre, 25 to 50 kg of potassium sulfate, and 2 to 5 kg of medium and trace element fertilizer. Mix the fertilizer and apply it, bury the soil, and pour the water once. Foliar application of 0.3% urea + 0.3% potassium dihydrogen phosphate + 0.1% borax or medium and trace element fertilizer (calcium magnesium boron zinc iron) solution for 1 to 2 times before flowering can promote pollination and fertilization. In the process of flowering the ear, the fruit grower should remove the small flower spike and cut off the auxiliary ear. About 5 days before flowering, 1/5 to 1/3 of the inflorescence tip was removed, and excessive inflorescences were eliminated. The strong branches leave 1 spike, and the weak branches do not leave fruit. Weeding and weeding should remove the weeds in the vineyard, cover the surface soil of the pineapple, cover the surface with grass, and arrange the drainage ditch to prevent water accumulation. Pest control In the prevention and control of pests and diseases, fruit farmers should pay attention to the spraying of 2.5% deltamethrin EC 3000 times and 10% imidacloprid 1500 times in the early stage of germination to control green blind mites and mites. Pre-flowering 500 times carbendazim or 500 times daisen zinc to prevent black pox, powdery mildew, downy mildew, etc., spraying about 10 to 15 days, pay attention to timely replenishment after rain.

The buds should be fixed to remove the improper buds, weak buds and over-bulbs, so that the buds are strong and well-positioned.
