Embodiment 1

[0016] A kind of compound fertilizer that is used for the strong branch of Merlot grape variety, is made up of the component of following parts by weight:

[0017] 25 parts of urea, 35 parts of diammonium phosphate, 5 parts of potassium sulfate, 35 parts of wine lees organic fertilizer (purchased from Sino-French joint venture Dynasty Grape Wine Co., Ltd.).

[0018] Application effect: by fertilizer efficiency contrast test, the results show: compared with conventional fertilizers, the leaves after using the compound fertilizer of the present invention are dark green, the branches are thickened by 0.1-0.12 cm, the bud eye branching rate is improved by 5-10%, and the length of branches is increased by 15%. --20 cm, the number of mature nodes increases by 2-3 nodes, and the proportion of strong bars increases by 10-15%, the effect is very obvious.

Abstract

The invention provides a compound mixed fertilizer for invigorating branches of a Merlot grape variety, which is prepared from the following components in parts by weight: 20-25 parts of urea, 30-35 parts of diammonium phosphate, 3-5 parts of potassium sulfate and 35-47 parts of wine lees organic fertilizer. In the compound mixed fertilizer, a relatively large amount of nitrogen and phosphorus and a proper amount of potassium are contained according to the requirements of plants for different growth and development periods, the wine lees organic fertilizer is used as the basis, and the long-term improvement on the soil structure and microenvironment is emphasized. The post-emergence application of the compound mixed fertilizer to a grape plant can obviously improve the growth potential of Merlot branches, thereby ensuring that the leaves are strong green and invigorate.

Description

technical field [0001] The invention belongs to the field of crop nutrients, in particular to a compound fertilizer used for strong branches of Merlot grape variety. Background technique [0002] Due to its outstanding quality, the wine grape variety Merlot has been widely valued by people in the international wine industry, and it has become one of the red wine varieties with the fastest growing planting area in the world. In recent years, with the rapid growth of dry red wine consumption, the planting area of ​​Merlot varieties in various regions of the country has been continuously expanding. [0003] The robustness of the branches of grape plants in spring is very important to the growth and results of grapes throughout the year, and it is the basis for high-quality and high-yield grape plants. However, Merlot has the characteristics of weak spring branching and poor growth potential. It is imperative to use compound fertilizer for strong branches of varieties. Conten...
