The difference of water demand of grape in different growing stages is obvious.

Before and after germination to flowering is the first water demand peak, the most suitable soil moisture is 65% ~ 85%.

Flowering period is generally not suitable for irrigation, otherwise it will aggravate physiological fruit drop.

If there is insufficient water during shoot growth and young fruit expansion, the yield will decrease significantly, which is the second peak water demand, and the most suitable soil moisture is 80% to 90%.

The fruit should supply sufficient water during the rapid expansion period, promote the growth of berries and increase the number of cells, but prevent too much water from forming new shoots.

Water in fruit ripening stage has a great influence on fruit quality, too much water will delay fruit ripening, quality deterioration, and affect the ripening of branches and vines, close to the harvesting period of about 15 days, generally not suitable for irrigation.

Grapes need many elements to grow. According to the test and production verification, the necessary elements are carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, and other 16 kinds, such as the lack or lack of one of them, it will affect the normal physiological activities, the application of other elements can not be replaced, only the lack of elements can be corrected, otherwise it will lead to deficiency disease and cause physiological disorders. Grape is a famous "potassium plant", the whole growth period needs a lot of potassium, although the absorption of potassium starts from the spread of leaves and shoots, but the fruit needs the most potassium from the hypertrophy to the coloring stage; This stage such as insufficient potassium, fruit color difference sugar low taste acid, serious even can not mature.

Integration of water and fertilizer

Grape is a fleshy root with high respiratory intensity and high oxygen demand. It is very important to improve soil structure, keep soil loose and increase soil oxygen content. In grape production, the traditional irrigation methods (shoulder hand watering and border irrigation) have low water resource utilization rate, coupled with the increasing water shortage caused by regional, seasonal, resource and pollution, the "water constraint" degree of grape production has intensified, and the grape irrigation problem has become increasingly prominent. It is urgent to change the traditional irrigation methods and promote advanced scientific and efficient water-saving irrigation technology.

The water and fertilizer requirements of grapes are mainly determined by their unique root system and water conditions

Grapes have high water requirements, and strict control of water in the soil is a prerequisite for growing good grapes. Grapes require more water in the early growth or vegetative growth period, and less water in the later growth or fruiting period, so it is necessary to avoid root damage so as not to affect the quality.

Grapes avoid rain and dew, rain for many years is easy to cause insufficient sunshine, photosynthesis is limited, too much water absorption is easy to cause branch growth and humidity is too high, easy to cause a variety of diseases, such as blackpox, gray mold and so on.

Therefore, during the flowering period, it is ideal to keep the branches at 40-70 cm. The amount of irrigation in fruiting period should also be controlled in areas prone to cracking. Water scarce and drought-prone areas should be properly covered with straw to maintain soil moisture and control grass growth.Classic Case

Henan Province Zhonghe National Agricultural Demonstration Park Project

Project brief: The park plans a new shelter to grow grapes, covers an area of nearly 1,000 acres. Each of the two adjacent sheep sheds is divided into a wheel irrigation area, and 209 cultivation tanks are planted to limit the growth of grape root fields. Microspray (5428 atomizing micro-nozzle) is mainly used in the tanks. The first equipment of the system mainly includes intelligent constant pressure frequency conversion control system, automatic backwashing sand/lamination filter system, Cloud intelligent fertilizer applicator.
