Abstract

The invention discloses an ecological cultivation method for grapes. The ecological cultivation method comprises the following steps of: (1) soil preparation; (2) germination stage management; (3) leaf expansion period management: starting leaf expansion from the last ten-day period of March to the first ten-day period of April, binding main stems, binding 3-4 branches for each plant, picking buds, spraying amino acid foliar fertilizer every 10 days, and performing spraying for 2-3 times, from the middle ten days of April, thinning shoots, removing small shoots, reserving large shoots, reserving 5-6 fruit branches for each plant, performing pinching, reserving 5-7 leaves on the inflorescence, and thinning flowers; (4) flowering period management: pruning, controlling the branches and the leaves, performing spraying 0.2-0.3% of a boric acid solution, thinning the branches after fertilizer spraying, and removing side shoots; (5) expansion period management: topdressing an organic fertilizer, spraying 20-25ppm gibberellin every 5 days, performing spraying for 2-3 times, performing fruit thinning management, and reserving only one cluster on moderate branches; and (6) fruit ripening: starting to harvest fruits in the first ten-days period of July. The use amount of pesticides and chemical fertilizers is greatly reduced, and green cultivation of grapes is achieved.

Description

technical field

[0001] The invention relates to grape cultivation techniques, in particular to an ecological cultivation method for grapes. Background technique

[0002] The excessive use of chemical fertilizers and pesticides in our country is serious. Due to the excessive use of pesticides and chemical fertilizers, we are facing a series of the most serious environmental pollution problems, including soil and water acidification, surface and groundwater resource pollution, and increasing greenhouse gas emissions. Typically, less than 1% of applied pesticides actually find their way into the target pests, leaving the rest to pollute air, soil and water. At present in China, the nitrogen absorption efficiency of rice, wheat, and corn is only about 26% to 28%, while the absorption rate of vegetable crops is less than 20%, and the rest is completely lost to the environment. The main reasons for the excessive application of chemical fertilizers and pesticides are: first, the l...

Examples

Embodiment 1

[0037] Example 1: Heat 500 parts of distilled water to 80-95 ° C, adjust the pH of the aqueous solution to 4-5, dissolve 0.5-1 part of matrine, 5-8 parts of polyvinyl alcohol and 1-2 parts of chitosan according to the amount Spray-dry in distilled water to prepare a composite insecticide with a particle size of 5-10 μm.

[0040] Take 0.3% matrine water as control 1, dilute 0.3% matrine water 800 times, focus on spraying on the middle and upper young leaves of grape plants, and the active ingredients of matrine applied in the remaining samples 1-5 and Contrast 1 is the same, distilled water is used as blank control, investigates the morbidity rate of grape plant from flowering stage to ripe stage, the results...

Embodiment 2

[0042] Example 2: During the leaf spreading period, the difference between the daytime temperature in the shed and the nighttime temperature in the shed affects the quality of the grapes. The blank control is the grapes grown at natural temperature. The rest of the treatment conditions are the same, and the chlorophyll content of the grape plants after entering the expansion period is measured. , the survey results of different varieties of grapes are shown in Table 2. From the results in Table 2, it can be seen that the stress resistance of grapes can be significantly improved, the growth of grape plants can be increased, and the grape Chlorophyll content in leaves.

Embodiment 3

[0045] Embodiment 3: the microbial bacterial fertilizer and calcium superphosphate are mixed in a mass ratio of 2:1, the microbial bacterial fertilizer is 10kg / mu, and the amount of calcium phosphate is 5kg / mu; At the bottom of the hole, spread urea on the upper layer of microbial fertilizer. The mass ratio of urea and microbial fertilizer is 1:1. Each grape is 20g of microbial agent, and urea is 20g / plant; the control is the amount of calcium phosphate used alone 5kg / mu, 10kg / mu, 15kg / mu, 20kg / mu and the rest are the same. The results are shown in Table 3.
