What is the vine limiting root cultivation technology
Do you understand these? The vine limiting root cultivation technology is a knowledge in the field of horticulture. Next, the editor will provide you with a detailed explanation.
What is the vine limiting root cultivation technology
It is believed that everyone has heard of vine limiting root cultivation. This cultivation method greatly reduces the area of soil tillage, fertilization, and irrigation, significantly saving the use of soil, fertilizer, and water, achieving semi-automation and labor-saving in fertilizer and water management, greatly reducing labor costs, improving fruit quality, and enhancing economic benefits. So, how to limit the root system of grapevines? What are the benefits of limiting root cultivation? Let's take a look with the editor.
What is vine limiting root cultivation
Vine limiting root cultivation is aimed at improving the control of root growth within a fixed space, regulating the nutritional growth and reproductive growth of the above-ground part, ensuring that more nutrients are loosely enters the fruit seeds, and reducing late fruit cracking. The yield per mu is also increased by more than 10% compared to conventional methods. The fruit sugar content is also increased by 2 degrees, and the planting cost can be saved by about 800 yuan per mu.
Key points of limiting root cultivation
This cultivation technology is carried out in soil with超高 organic matter content to ensure the quality of root growth and respiration; it is completely different from the conventional cultivation of fertilizer and water management. In conventional cultivation, fertilizers enter the soil and are absorbed by the roots through the soil's buffering effect, while limiting root cultivation involves direct contact between fertilizers and roots, roots are restricted within a certain range, promoting massive absorption and improving fertilizer absorption and utilization efficiency; due to the direct contact between fertilizers and roots, it is necessary to adopt integrated fertilization and irrigation (G-Y). The concentration of the fertilizer solution must be limited to avoid root damage caused by high concentrations. At the same time, the content of heavy metals and other harmful substances in the fertilizer solution must be limited; in the early stage of this cultivation technology, there is no need to apply fertilizers at the base. After 3-4 years of cultivation, appropriately expand the plate and supplement with enhanced water-soluble organic fertilizers.
Vine limiting root cultivation techniques
1. Ridge cultivation
Refers to laying microporous non-woven fabric plastic film on the ground, piling soil rich in organic matter on top to form ridges, and then planting grapes on the ridges. This method is suitable for areas with less soil freezing, but poor soil moisture and temperature stability in summer.
2. Box basket cultivation
Using box basket structure or brick structure facilities as limiting root cultivation containers, filling mixed soil to cultivate grapes, the bottom edge of the box frame can be left with excess moisture to avoid waterlogging. The disadvantage of this method is that the root system
3. Pit cultivation
Dig a volume pit on the ground. The sides and bottom of the pit are lined with porous non-woven fabric and other permeable but root-impermeable membrane materials. Fill with nutrient-rich soil and plant trees inside.
