Grape Cultivation and Management Techniques
The editor provides you with some small experiences in plant breeding, including grape cultivation and management techniques and a complete guide to greenhouse grape planting techniques, as follows:
I. Management During the Dormancy Release Period of Winter Early Cultivation
In mid-to-late October, when grape leaves have not been damaged by frost, spray a solution of 200-300 times the concentration of 80% Necessary or a 1:0.7:100 Bordeaux mixture, and then water. After that, cover the greenhouse and start artificial centralized pre-cooling treatment to maintain the temperature inside the facility as close as possible to 0-9 degrees Celsius. During this period, retain the leaves to fall naturally, and after the leaves fall, promptly prune according to the variety characteristics and shaping requirements.

II. Management During the Germination Promotion Period of Winter Early Cultivation
When the cold requirement of the grape variety is met by 2/3 to 3/4 (generally 25-60 days), start heating during the day by uncovering the straw mulch, immediately water, and after 2-3 days of heating, apply a grape dormancy-breaking agent to the dormant buds or branches to promote the release of grape dormancy, ensuring that the grape germination is normal and uniform; 12-15 days after heating, spray a 3-degree Baumé lime sulfur mixture to eradicate residual pathogens. Temperature control during this period is very important. It is necessary to warm up slowly to coordinate the warming of air and soil temperatures. At the same time, maintain higher soil and air humidity. Temperature control standards: the first week, 15-20 degrees Celsius during the day and 5-10 degrees Celsius at night; the second week, 15-20 degrees Celsius during the day and 7-10 degrees Celsius at night; from the third week to germination, 20-25 degrees Celsius during the day and 10-15 degrees Celsius at night. The period from heating to germination is generally controlled within 25-35 days. Humidity control standards: the relative humidity of the air should be above 90%, and the soil relative humidity should be 70%-80%. Water again after germination. At this time, you can apply a nitrogenous fertilizer such as urea, but if the tree is well-nourished, it may not be necessary. Then cover the whole garden with plastic film to reduce air humidity and minimize or prevent disease occurrence.
