As the pace of spring fades away, in the fields at an altitude of about 1,800 to 1,900 meters, this article is written by Jiang Shaolong, a senior agronomist in the old town and countryside of Yuanmou County, to explain how to manage the low temperature weather, but it is still raging, which has brought a lot of trouble to grape growers.
Recently, the phenomenon of grapes running out of flowers in many areas has been serious, which has made growers worried. In response to this problem, measures to deal with the low temperature weather grape flowering, in order to help the majority of growers. 1. Strengthening vineyard management 1Raise ground temperature: Cover the vines with white mulch to increase the ground temperature. At the same time, reduce the frequency of watering and supplement more microorganisms to increase the ground temperature. Strengthens the activity of the grape root system. 2.Fertilizer and water management: Proper fertilization and irrigation to ensure the water and nutrients of the vines in cold weather**. 3.Pest control: Strengthen pest control to reduce grape flowering caused by pests and diseases. 2. Adopt cold-proof measures 1Mulching: Mulching the vineyards before the onset of cold weather to reduce the loss of ground temperature and raise the soil temperature. 2.Water spraying: During low temperature weather, spray water on the vines, taking advantage of the large specific heat capacity of the water, which can absorb more heat and increase the air temperature around the vines. 3.Smoke: Before the arrival of low temperature weather, smoke is used to increase the moisture content in the air, improve the humidity of the air, and reduce the occurrence of grape flowering. 3. Variety selection and improvement Select grape varieties with strong cold resistance for planting to improve the adaptability of grape vines to low temperature weather. At the same time, through grafting, breeding and other means, the existing varieties are improved to improve their cold resistance.
The plan of the year lies in spring: the first task of spring ploughing is to promote the early awakening of roots and more roots of plants under the condition of low ground temperature.
Among them, the number of roots in spring directly affects the yield and quality of the year!
