The Latest Methods for Root-Controlling Vegetable Seedlings Explained in One Article
Vegetable cultivation is distributed throughout China. When growing vegetables, we need to do a good job of root-controlling the seedlings during their seedling stage. Root-controlling seedlings can enhance the growth capacity of vegetable seedlings and lay a good foundation for the later growth of the vegetables. However, many people do not know how to control the roots of seedlings, so how exactly should vegetable root-controlling be done? Today, the editor brings you the methods for root-controlling vegetable seedlings. Let's take a look together below!
1. Fertilizer and Water Control During the Seedling Stage
The most important part of root-controlling vegetable seedlings is to control fertilizer and water well during the seedling stage, ensuring that the plant internodes gradually become short, thick and sturdy and that the roots develop well. Be sure to reduce the amount of fertilizer and water; if there is too much fertilizer and water, it will be very unfavorable to the growth of the vegetable roots. Controlling fertilizer and water can ensure that the vegetable roots effectively penetrate deep, and at the same time can improve the stress resistance of the seedlings. However, before starting root control, you should still water thoroughly to ensure that the seedling roots can combine with the soil. Then, within one week after transplanting, do not water; but if the temperature is too high and the leaves droop due to lack of water, then you should still water appropriately to avoid the soil drying and cracking.
2. Soil Cultivation
Cultivating the soil is also one of the main methods for root-controlling vegetables. Cultivation can cut off the capillaries in the soil, ensure that the soil surface is soft, and at the same time improve the storage capacity of the lower soil, which is very beneficial to the vertical extension of the root system. Moreover, during cultivation, because some lateral roots will be cut off, the crop's ability to absorb nitrogen and its metabolism are reduced, and the accumulation of carbohydrates in the crop is increased, which is very beneficial to crop growth and can effectively reduce excessive vegetative growth.
During cultivation, pay attention to controlling the number of times and timing according to the crops planted, the growth of the seedlings, and the actual condition of the soil. If dryland crops are planted, then it should be done during the seedling stage and before row closure; while for crops such as rice, it should be done during the tillering stage. Generally, crops in one season require about 3 cultivations. However, if the crop's growth period is long, row closure is late, and the soil is sticky, heavy and not permeable, then the number of cultivations can be appropriately increased to ensure that the ground is free of weeds and soft. Finally, during the crop seedling stage, cultivate shallowly; in the middle stage, appropriately deepen to ensure root growth; and before row closure in the later stage, shallow cultivation is preferable.
3. Root-Control Methods and Timing
When we determine the timing and methods for root-controlling vegetable crops, they will differ depending on the crop. For example, if it is a spring-sown crop such as sorghum or corn, then root control is generally carried out from the final thinning of seedlings to the jointing stage, and the main method is to scrape away soil and expose the roots to the sun. For some vegetables raised as seedlings and then transplanted, the amount of watering should be controlled while they are in the seedbed, and the seedlings should be subjected to drought hardening. Temporary planting can also be carried out to inhibit the growth of the aboveground part of the crop and improve its resistance to changes in the external environment.
