how to properly grow and maintain the roots?

When it comes to rooting vegetables, vegetable farmers have paid enough attention to it, but many do not have a very clear concept of how to properly grow the roots. There are still many misunderstandings about vegetable rooting, so how to properly grow and maintain the roots?

Misconceptions about vegetable rooting
1. Excessive use of rooting agents. Blindly using rooting agents, thinking that more rooting agents should be used to promote rooting, is actually a wrong approach.
2. Focusing on promoting new roots but not on maintenance. Excessive use of rooting agents or when the root quantity is small after root injury or root disease is cured or the growth is in the late stage, in order to promote new roots in a short time, it is sometimes recommended to use hormone rooting agents. After application, new roots grow rapidly, but when vegetable farmers see new roots, they think that they have considerable water and fertilizer absorption capacity, thus ignoring the maintenance of new roots.
3. Plucking leaves too early and too hard will cause premature aging of the root system. The roots are nourished by leaves. If there are too few leaves, the nutrients accumulated through photosynthesis will be less. The root system is prone to premature aging, and the ability to absorb nutrients will be greatly weakened. The fruit will not receive enough nutrients, and the color change and expansion will be affected, resulting in a decrease in yield and quality. Therefore, it is recommended to only remove the old leaves and keep at least 5-6 nutrient leaves to allow the plant to accumulate photosynthesis normally.

So how do you properly root and nourish the roots?

1. The planting method should be reasonable. Furrow planting, bed planting and ridge planting are the main planting methods used by vegetable farmers. For areas with high groundwater levels, high ridge planting is preferred. For areas with low groundwater levels, the above three planting methods can be used, but flat bed planting is better for summer cultivation, while furrow planting or ridge planting is more suitable for planting at other times, especially for large-scale planting.
2. After the seedlings have been grown, water should be controlled and hoeed. Everyone knows that the root system is hydrophilic. Water control is conducive to the root system to grow deep. Therefore, after the watering for the seedlings has been applied, water control should be adopted in management. Depending on the soil conditions, plant growth and weather conditions, the water control time is about 15-20 days. In order to obtain the water needed for the growth and development of the plants, we can hoe them. Generally speaking, we need to hoe them at least twice from the time of seedlings growing to the time of fruiting. The first time is after the watering for the seedlings has been applied, and the hoeing starts when the surface is dried. The second time is about 10 days after the seedlings have been grown.
3. Covering the ground film late Covering the ground film late can promote the root system to grow deep, so that the root system will not be greatly affected when the cold current comes, and the plant has strong cold and frost resistance. When planting vegetables in the low temperature season of winter and spring, in order to prevent the low air and ground temperature from affecting the growth of vegetables, you can first set up a small arch shed for insulation, and then cover the ground film after about 15 days. Do not cover it too early.

4. Ground temperature should be appropriate. First of all, we should understand that ground temperature refers to the temperature of the soil 5 cm below the surface! In high temperature periods, the ground temperature should be appropriately lowered; in low temperature stages, the ground temperature should be appropriately increased. Effective measures to increase ground temperature mainly include: increasing the temperature in the shed; using straw bioreactors; and watering and fertilizing properly.

6. Leaf maintenance Leaf maintenance should be divided into two aspects: one is maintenance, the other is protection. 1. Maintenance: Generally speaking, it is to spray foliar fertilizer. Under normal circumstances, you can spray humic acid water-soluble fertilizers such as Yejiangen rooting and rooting agent on the leaves. For flushing, you can use Yejiangen rooting and rooting mother powder to achieve the effect of rooting, rooting and protecting the roots.
2. Protection: that is, leaf area, mainly including pruning and leaf picking, disease prevention and pest control. Regarding pruning and leaf picking, we should do it in batches, not pick too many leaves at one time, and it is not advisable to remove the old leaves at the bottom rashly.
The principle of leaf picking is to pick the yellow leaves and not the green leaves, pick the lower leaves and not the upper leaves, pick the inside and not the outside, and pick the diseased, yellow leaves, old leaves, and dense leaves in batches.
