Fertilization and branch management method for grape planting

Abstract

The invention discloses a fertilization and branch management method for grape planting. A planting technology is implemented by the following steps: 1) fertilization in autumn, to be specific, uniformly mixing and burying 1,500 to 2,000 kilograms of chicken manure and 2 to 3 kilograms of biological fertilizer into the soil of every acre from the end of September to the first third of October after fruits are picked in autumn; 2) application of sprouting fertilizers, to be specific, applying 10 to 15 kilograms of compound fertilizer to every acre in a pouring way before March 10 every year, and applying 6.5 kilograms of boric fertilizer in holes of every acre, wherein the mass ratio of N to P2O5 to K2O in the compound fertilizer is 1:1:1, and the total mass content of N, P2O5 and K2O is not lower than 45 percent; 3) application of fruit swelling fertilizers, to be specific, applying 5 kilograms of zinc sulfate and 8 kilograms of magnesium sulfate to every acre a week after flowering, and applying 25 to 30 kilograms of compound fertilizer to every acre 18 to 22 days after flowering every year, wherein the mass ratio of N to P2O5 to K2O in the compound fertilizer is 8:4:9; 4) spraying application of microelement fertilizers to leaves, to be specific, (1) diluting a 20 percent boron and zinc microelement fertilizer by 1,000 to 1,500 times, and applying the diluted microelement fertilizer twice to the leaves at an interval of 10 to 15 days 18 to 22 days after the germination of grapes; (2) diluting a 15 percent organic selenium-rich leaf fertilizer by 500 times, and applying the diluted leaf fertilizer twice at an interval of 12 to 15 days 25 to 35 days before the maturing of the grapes; 5) branch management in a growing period; 6) branch pruning, to be specific, performing short branch pruning in winter.

Description

technical field [0001] The invention relates to a planting technology, in particular to a fertilization and branch management method for grape planting, and belongs to the technical field of agricultural planting. Background technique [0002] Ordinary wine grapes grow relatively slowly and need to be planted closely. Grape fruit growth period is about 135 days to 150 days. The disease resistance is not strong, it is not suitable for growing in rainy and humid places in the south, and it is not resistant to phylloxera. The production requires a lot of labor, and the number of pests and diseases is prevented every year. The quality of grapes varies greatly due to external natural and human factors. It is difficult to ensure consistent fruit quality in large-scale cultivation. Contents of the invention [0003] The present invention proposes a fertilization and branch management method for grape planting, which greatly saves labor, reduces planting costs, improves survival...
