Squatting seedling method

Squatting seedling is a traditional crop management technique, which is a technical measure to restrain the excessive growth of stems and leaves of seedlings and promote the development of roots in crop cultivation. So, what is the method of squatting seedlings?

What is the method of squatting seedlings?

There are two common methods of squatting seedlings, one is to control the fertilizer and water at the seedling stage, so that the plant internodes tend to be thick, short and strong, and the root system is developed. The second is to carry out multiple mid-tillage to make the surface soil loose and dry, and the lower layer water preservation is good, which is conducive to root elongation, control overgrowth, increase the accumulation of carbohydrates in the plant, and make it grow healthily.

Measures for squatting seedlings also include plucking the soil and drying the roots to improve the ground temperature. The period and specific operation methods of squatting seedlings vary from crop to crop. Sorghum, corn and other spring sowing crops generally carry out soil and root drying before seedling setting to jointing; most of the crops and vegetables transplanting seedlings are controlled watering in the seedbed, drought training, or pseudo-planting of seedlings, so as to restrain the growth of aboveground vegetative organs, enhance the resistance to external adverse conditions, and shorten the slow seedling period after transplanting.

Second, the benefits of squatting corn seedlings

The main results are as follows: 1. Controlling the plant growth potential can make the aboveground part of maize seedling grow slowly, promote its growth robust, shorten the node and resist lodging.

2. Promoting the development of the root system can make the root system of the underground part of maize developed, deeply rooted in the ground, improve the lodging resistance of the plant, enhance the root activity and the ability of absorbing nutrients and water, inhibit vegetative growth and promote reproductive growth.

3. The experiment of increasing the yield of corn shows that the yield of corn can be increased by 7% and 12% after squatting seedlings.

Matters needing attention in squatting corn seedlings

1. Corn squatting seedlings should master the principle of "squatting black without squatting yellow, squatting fat without squatting thin, squatting wet without squatting dry". Is the seedling color black and green, soil fertility fertilizer, soil moisture good land can squat seedlings, on the contrary, do not squat seedlings, but should take partial fertilizer, partial water management.

two。 Generally, the time of squatting seedlings is from emergence to jointing stage.

The period and specific operation methods of squatting seedlings vary from crop to crop, and we can understand the growth of crops before squatting seedlings.
