Vegetable seedlings promote root growth

As the saying goes, the roots are deep and leafy. To grow vegetables and grow strong, we must first have a strong root system. The most critical period for cultivating a robust root system is the seedling stage, since the root system that is created at this time is the “skeleton” from which the root system grows. If the root system is shallow at the seedling stage, the root system is shallow during the entire growth period, and the shallow root system The impact of environmental changes such as watering, drought, and ground temperature is the most direct and most vulnerable.

Pouring the first three waters and drawing them in succession

The root system has obvious water and fat properties. It is necessary to guide the deep rooting of the root system. Watering during the seedling stage must be paid attention to. The experience of vegetable farmers can be summed up as “small water for colonization, large water for seedlings, and late for water”. After you promote the water, until the new leaves are dark, and then watered before and after noon, you can cause drought on the surface and guide the roots to lower. From the time of colonization, every time after watering, it should be cut in time to break the surface compaction caused by watering, reduce the surface humidity, and promote deep roots. Scratching should follow the principle of “close to the seedlings, shallow in the later period, distant in the distance, and deep in the early stage” to ensure the purpose of achieving less wounds and roots and good soil permeability.

Late cover film

Many vegetable farmers are used to cover the plastic film immediately after planting. In fact, this is unfavorable to the growth of vegetables, especially the overwintering and picking vegetables that grow for a long period of time. The mulch film should be supported by steel wire or slings and should not be attached to the ground so as not to affect the air permeability of the soil.

Rational seed dressing

From the start of sapling seedlings, functional root-fertilizing fertilizers can be formulated to promote rapid root growth and facilitate rapid seedlings and cultivating strong trees. When water is poured to promote the water, organic water-soluble fertilizers such as amino acids, seaweed fertilizer, humic acid, chitin, and biological agents can be flushed with water to protect the root system.

Doing the seedling control

It should be noted that there are few leaves at the seedling stage, and there are fewer nutrients to be produced, and the aboveground plants will grow faster and consume more nutrients. Therefore, the nutrients obtained from the root system will be relatively reduced and the activity will be weak. Therefore, in seedling management, the control of the above ground is to promote root growth. Especially after the summer and autumn vegetables are planted, the temperature inside the greenhouse is high, and the vegetables are prone to affect the flowering and fruiting in the later period. Generally grown in vegetables to 4 to 6 leaves, in the initial stage of vigorous growth, according to the growing plant, in advance sprayed Qian Zhuangsu 500 to 800 times control Wang.

Laser Tape Measure
