Green onion is a kind of vegetable with good fertilizer. After entering the autumn, the suitable temperature and humidity make the green onion enter a period of rapid growth. During this period, the green onion should be scientifically used to raise fertilizer and create a good growth environment for the formation of green onion, thus improving the quality of green onion. Yield. So how to fertilize the onion to grow more lush? How to topdress the autumn green onions? The following series of Hui Nongwang will give you a detailed introduction to the autumn onion method.
First, how to topdress the autumn green onions
For a long time, many vegetable farmers have used the method of ditching to give the green onions a top dressing. This is unscientific. Because it is not only possible to cut off the roots of the green onions, but also because the fertilization is too concentrated, the young roots of the green onions burn out and the dry and dead leaves occur, affecting the quality and yield of the green onions, so it is not recommended to open Ditch pursuit.
The correct fertilization method for autumn onion should be: follow the principle of “small number of timesâ€, adopt the method of soil fertility, and 3-4 times from the planting of the green onion to the harvest, so as not to defer the growth of the onion. Fertilize 20-30 kg per mu, or 10-15 kg of urea and potassium sulfate; according to the growth period of green onion, the amount of fertilizer should be slightly more than the previous one; when the onion is topdressed, the fertilizer should be evenly applied to the root of the onion. On the surface, then the soil is covered with fertilizer to reduce the loss of fertilizer volatilization, promote the whitening softening and elongation, and enhance the wind resistance of the green onion. After the green onion is fertilized, water should be poured once in two days to make the fertilizer dissolve better in the soil and decompose rapidly, and promote the growth and development of the green onion.
Second, autumn green onion production management points
1. After the autumn, the temperature gradually decreases, and the absorption function of the roots of the scallions turns into a vigorous period. The green onions will enter the peak of the hairy leaves, and the need for water and fertilizer will increase. During the period from Liqiu to Bailu, the watering should be “light pouring, early and late pouringâ€. Principle, combined with watering and application of "grazing leaf fertilizer", green onions per mu apply 1500 kg of decomposed farmyard manure, 20-25 kg of superphosphate, 10 kg of potassium sulfate to promote the rapid development of the leaves.
2, after the white dew, the weather is cool and the temperature difference between day and night increases, the green onion enters the critical period of onion formation. At this time, it is also the key period of fertilizer and water management. In the white dew to autumn, the topdressing should be based on quick-acting nitrogen fertilizer, and urea as the good, per acre. About 20 kg is appropriate, and 15 kg of potassium sulfate is added. Watering should be based on the principle of “during pouring and re-casting†to keep the soil moist and meet the growth and development needs of scallion.
3. After the frost falls, the weather is getting colder, the growth of the green onion leaves is slower, and the water transpiration of the leaves is reduced. At this time, the watering should be gradually reduced, and the watering should be stopped 7-8 days before the harvest, in order to improve the tolerance of the green onions. Storage.
The above is the autumn scallions topdressing method for Hui Nong. I hope that everyone can grasp the fast growing season of green onions and do the autumn topdressing work, so that the green onions grow more lush.
