Onion as a popular vegetable variety has a large consumer group. After the harvest was completed, it was time for the vegetable growers to plant autumn green onions. Here, we will introduce the high-yield cultivation techniques of autumn green onions for your reference.

First, choose the best species

In the main producing area of ​​autumn scallions in the middle and southern part of our province, we often choose good varieties with good yield, strong disease resistance, and spicy pungent flavors such as chicken and scallions.

Second, the mouth arrangement and plot selection

The green onions are extremely intimidated by serials, and the masses have the saying that “spicy is hot, must be cooked, and garlic must not be seen”, so scallions cannot be re-picked with vegetables such as garlic, leeks, and onions in the production of cornices. But with cabbage, eggplant, melon, watermelon, cabbage intercropping or picking. The plots on which green onions are grown should be selected for soils rich in organic matter, deep in soil, high in dry ground, and conducive to drainage. The green onions grown on such plots have a spicy taste, full flavor, and high yield.

Three, soil fertigation

Apply enough base fertilizer to apply 5,000 kg of composted high-quality fertilizer, 50 kg of superphosphate, and 30 to 40 kg of ternary compound fertilizer per acre. Spread the above fertilizer evenly on the surface, and then plunge 20-30 cm deep. The ditch is 30 cm deep.

Fourth, colonization

In the middle and southern plains of our province, the most suitable time for planting autumn green onions is in early July. The method of transplanting is often used in production. First, the nursery bed is watered 1 to 2 days before the seedling raising, so as to keep the soil dry and wet, it is not difficult to lift the seedlings, and soil is not attached. Do with the seedlings, with the planting seedlings. When planting seedlings, the depth is not buried in the heart, in the ground exposed 7 ~ 10 cm is appropriate, due to the size of onions and oysters, should be consistent with the lower part can be maintained. Generally, high-yielding fields cover 13,000 to 16,000 planted acres. The principle is: the fertilizer should be thin and the soil should be dense; the fat should be thin and the fat should be dense. In order to facilitate soil cultivation, the method of enlarging the row spacing and reducing the plant spacing should be adopted. That is: more than 70 cm line spacing, spacing between 5 to 8 cm.

V. Post-planting management

1. Slow seedling management. After the green onion seedlings were planted, the old roots soon rotted, and new roots sprouted after 4 to 5 days. New roots grew and new leaves began to grow. The management objective of this period is mainly to promote the development of the root system. One is to prevent flooding and the other is to loosen land. If there is water in the trenches after the rain, it will often cause yellowing of the onion leaves and dead roots. Therefore, it is necessary to drain the water and cultivate the soil in time after the rain.

2. The management of the growth period. After the beginning of autumn, the temperature gradually decreased, and the root absorption function was transferred to a vigorous period. After entering the peak period, the need for water and fertilizer increased. During the period from the beginning of autumn to Bailu, the principle of watering was “light pouring, early and late pouring,” combined with watering. Topdressing “Loft of leaf attack”, applying about 1500 kg of farmyard manure per acre, 20-25 kg of superphosphate, 10 kg of potassium sulphate, to promote the rapid development of leaves. After the white dew, the weather is cool, the temperature difference between day and night increases, green onions into the light blue and white formation period, is also a critical period of fertilizer management, in the white dew to the equinox, topdressing with fast-acting nitrogen fertilizer, with urea as the best, about 20 kg per acre Shi It is appropriate to add 15 kg of potassium sulfate. The principle of watering is "diligence, heavy pouring," and often keep the soil moist to meet the growing needs of light blue. After the frost falls, the weather is getting cooler, the leaf growth is slowing, and the transpiration of the leaf surface is reduced. Watering should be gradually reduced. The watering should be stopped 7-8 days before harvest to improve the storability of Welsh onion.

What is healthy and sub-healthy

A lot of people think it is healthy as long as if only not getting sick, some people think it is healthy when every part body function are normal.
