Embodiment 1

[0018] The fertilizer containing ammonium bisulfate, calcium sulfate and monocalcium phosphate is dissolved in water according to the ratio to obtain irrigation water. Irrigate 2 times during the germination period in spring, 3 kg / mu each time, 2 times during the flowering and fruit setting period, 3 kg / mu each time, 3 times during the fruit expansion period, 5 kg / mu each time, and 3 times during the berry ripening period. Once, 5 kg / mu each time, water once after receiving the goods, 8 kg / mu each time. Stop irrigation 15-20 days before harvest.

Embodiment 2

[0020] The fertilizer containing ammonium bisulfate, calcium sulfate and monocalcium phosphate is dissolved in water according to the ratio to obtain irrigation water. Irrigate 2 times during the germination period in spring, 3 kg / mu each time, water 2 times during the flowering and fruit setting period, 5 kg / mu each time, water 2 times during the fruit expansion period, 5 kg / mu each time, and water 3 times during the berry ripening period. Once, 5 kg / mu each time, water once after receiving the goods, 8 kg / mu each time. Stop irrigation 15-20 days before harvest.

Embodiment 3

[0022] The fertilizer containing ammonium bisulfate, calcium sulfate and monocalcium phosphate is dissolved in water according to the ratio to obtain irrigation water. Irrigate 2 times during the germination period in spring, 3 kg / mu each time, water 2 times during the flowering and fruit setting period, 5 kg / mu each time, water 3 times during the fruit expansion period, 5 kg / mu each time, and water 3 times during the berry ripening period. Once, 8 kg / mu each time, water once after receiving the goods, 8 kg / mu each time. Stop irrigation 15-20 days before harvest.

[0023] After using this method for irrigation, its economic benefits are shown in the table below:

Abstract

The invention discloses an irrigation method for grapes. The irrigation method comprises the steps of dissolving fertilizers in water, carrying out irrigation, carrying out irrigation twice at a germination stage in spring, carrying out irrigation twice at a blossoming and fruit setting stage, carrying out irrigation for 2 to 3 times at a fruit swelling stage, carrying out irrigation for 3 times at a berry ripening stage, and carrying out irrigation once after harvesting. By using the irrigation method disclosed by the invention, the nutrient availability can be improved; the nutrient absorption of the grapes is enhanced; the supply volume of the fertilizers and water is reduced; the loss of moisture and nutrients is reduced; the damage to root systems and leaves of the grapes caused by saline matters is prevented; the hardening of soil is reduced; and the infestation caused by weeds, the pollution to underground water caused by the fertilizers, and the like are reduced.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a grape irrigation technology. Background technique [0002] Grape is a temperature-loving fruit tree with poor cold resistance. Only when the temperature rises to 10°C does it start to grow, and the optimum growth temperature is above 18°C. The germination stage requires a lower temperature of 10-12°C, the flower bud differentiation stage requires a higher temperature, and the optimum temperature is 25-30°C. If the temperature is lower than 14°C, the normal flowering of grapes will be affected. The optimum temperature in the ripening period is 28-32°C, and the fruit will not be fully ripe when the temperature is lower than 15°C. For areas with low winter temperatures, care should be taken to prevent freezing damage when grapes are overwintering, especially the root system of grapes is poor in cold resistance. Generally, some varieties can be frozen at around ...
