Grape root pruning and promoting technology

Abstract

The invention discloses a grape root pruning and promoting technology. The roots of grapes are pruned in sunny weather of each autumn, and a trench which is 30cm deep and 30cm wide at the distance of30cm from the main root of the grapes is dug; all roots in the ditch are cut off and then exposed for 3 to 7 days; after the notches are dried; 2 to 4 tons of organic fertilizer and autumn fertilizerof 2 to 5kg of trace elements such as boron, zinc and iron are applied per 667m2. The invention chooses to root in the autumn, at which time the root cutting does small damage to the plant, and the removal of the invalid roots reduces the nutrient consumption of the roots; the new roots have strong ability to absorb water and fertilizer, and the plants store enough nutrients. The tree growth in the next year is fast, the growth is strong, and the plant's ability to resist pests and diseases is enhanced. Through the exposure to promote the formation of callus, the new root formation time is short, the amount of rooting is large, and the new roots are 2 to 3 times stronger than the old roots. The addition of autumn fertilizer improves the agglomerate structure of the soil and increases the quantity and vitality of beneficial organisms in the soil.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a grape root pruning and promoting technology. Background technique [0002] The root system is an important organ for green plants to fix and absorb water and nutrients. The number of surface roots of grapes is large and the life span is short. After the peak of activity, nutrients are consumed in vain, which has a great impact on the overall structure and distribution of the root system. Strengthening root system management is particularly important in production. [0003] As an important measure, root pruning technology is used intentionally or unintentionally by farmers, but there is little research on it. Root pruning can remove invalid roots of plants, stimulate the production of lateral roots, renew old roots of plants, and improve root vitality and absorption capacity. During production, some farmers’ root pruning methods were not appropriate, causing the root system...

AI Technical Summary

Problems solved by technology

During production, some farmers’ root cutting methods are not appropriate, causing the root system to be twisted, the total amount of root cutting is too large, and the root system is damaged, or the timing is unreasonable and the sun exposure is not paid attention to, and the wound is covered with soil before the wound is healed, which does not play a positive role in root cutting.
