What are the key management points for chives during the summer high-temperature period

Chives are a common vegetable for us. In rural areas, basically every household grows them. They can be eaten in many ways and are also a common delicacy in the barbecue industry. But in summer, chives are at their most unpalatable. This is because the high-temperature climate in summer leads to low nutrient accumulation in chives, while the consumption needed for growth is high, which increases the fiber in the leaf tissue, making it rough and causing the taste to decline. So how should they be managed in summer so that their taste does not decline? Let's take a look with Qinnongwang.

1. Stop harvesting

During the summer high-temperature period, because chives accumulate few nutrients and consume a lot of nutrients, the fiber in the leaf tissue increases, causing the taste to become worse, so at this time harvesting generally should be stopped, specifically from June to August. Moreover, after chives enter the high-temperature period, they will show a summer dormancy phenomenon and thus stop growing. If harvesting is carried out at this time, it will have a certain impact on the growth and yield of chives after summer.

2. Weeding

In the summer high temperatures, chives themselves consume a lot, and if a large amount of weeds grow in the field at this time, they will compete with chives for nutrients and water, making the growth of chives even more unfavorable. So timely weeding at this time is beneficial to the growth of chives. In addition, during weeding, appropriate topdressing can also be done to supply what chives need for growth. Among the people, it is often practiced to add a handful of cooked soybeans at the base of chives, which is better than fertilizing and also greener than fertilizer.

3. Prevent lodging

Summer is hot and rainy, and for chives that have grown for more than two years, if no-harvest measures are taken, the chive plants will become tall with dense leaves, making them prone to lodging, leading to poor air permeability and easily causing diseases. Therefore, in order to prevent chive lodging, reduce diseases, and allow them to grow smoothly, supports should be set up for them.

4. Remove bolts in time

During the summer high-temperature and drought period, chives are prone to bolting. If the chive bolts are not removed in time at this time, they will consume a large amount of nutrients during growth. So when chives bolt, removing the tender bolts in time can avoid chives consuming a large amount of nutrients, cultivate robust plants, and the young bolt parts also taste quite good, and can be sold or eaten by oneself.

5. Pests and diseases

Summer is hot and rainy, and this environment very easily causes chives to develop Fusarium wilt and pest damage, leading to leaf withering and death, affecting later growth and yield. Therefore, attention must be paid to the prevention and control of pests and diseases. For Fusarium wilt, 50% carbendazim 500-fold solution can be used for root drenching. At the same time, after the heavy rain season, drain water in time to prevent waterlogging, remove diseased leaves or yellow leaves, maintain air permeability, and reduce the occurrence of diseases.
