Detailed introduction of cultivation management techniques of chives
The chives are also called seasons and onions, because the tender leaves of the scallions and the meat of the pseudo-stalks are very delicious, and the taste is also very special. It is a very good seasoning vegetable. Generally, it can be carried out in greenhouse cultivation in spring, autumn and winter. Let me talk about the technical points of cultivation and management of chives.
First, choose the variety
The chives are basically plantable all year round. They prefer a cool climate, and are not resistant to drought or heat. Therefore, spring and autumn are the main seasons for cultivation. The variety of chives should be selected to be adaptable, cold-resistant, and more resistant to heat.
Second, the selection and finishing of fine scallions
Shallots are vegetables that are cold-tolerant, so a suitable growth temperature is 15-25 °C. The cultivated plots should be soil with convenient drainage and organic matter. First, the base fertilizer should be applied. After spreading evenly, the whole land should be flat and there should be drainage ditch around. If it is cultivated with chives, it is best to plant it in spring and autumn.
Third, the sowing of chives
According to the different flowering and seeding, the method of breeding is also different. You can breed according to the specific situation. After the chives are propagated, the viable plants can start to divide. However, if the number of tillers is too much, the growth of the ground and underground parts of the chives will be inhibited. It is best to dig up the chives and replant the plants.
4. Field management of fine shallots
1. The moisture of the shallot should not be too much. The time before and after the emergence of the seedlings is as long as the soil is moist, and the seedlings are to the 1-3 leaf stage, the amount of watering must be controlled.
2, the transplanting time of chives should be selected 40-50 days after sowing, every 3-4 bushes when transplanting, the planting depth is about 4-6cm, timely planting water.
3, the root system of the scallions is relatively shallow, not resistant to heavy fertilizer, so it must be poured in small water, light fertilizer and diligent application, can be combined with fertilization and watering once every half a month to keep the soil moist.
4, about 15kg before the harvest of the chives can be applied about 15kg of urea, pay attention to rainwater drainage, one month after transplanting can be successively harvested.
Finally, from the time of transplanting to harvesting, it takes about 70 days for the chives to be harvested. When harvesting, you can choose a more robust chives plant as the next cultivated plant.
