What are the latest precautions for growing Chinese chives in summer?
Chinese chives are a common vegetable with many ways to eat them, and they are also a common delicacy in the barbecue industry. They can be planted all year round, but when planting in summer, several points must be noted, otherwise it will have a huge impact on their yield and quality. Below, join the editor to take a look at the precautions for growing Chinese chives in summer.
1. Clear weeds
Summer has high temperatures and frequent rain. This is a good season for Chinese chives to grow, and it is also a period when all kinds of weeds grow. Because Chinese chives plants are relatively low, they cannot provide effective shade, and combined with the spacing between rows, this creates favorable conditions for weed growth. Therefore, pay attention to clearing weeds in time, so that weeds do not compete with Chinese chives for water and fertilizer and affect their growth. After each watering, cultivate in time, which can both break up soil crusting and achieve the purpose of clearing weeds in time. In addition, during daily management, remove weeds whenever you see them, to benefit the growth of Chinese chives.
2. Control excessive growth
Chinese chives grow vigorously in summer, so many growers apply fertilizer irregularly in order to enhance nutrient storage in Chinese chives. This can very easily lead to excessive growth of Chinese chives, especially when too much nitrogen fertilizer is applied, making excessive growth even more likely. When excessive growth occurs in Chinese chives, plant height clearly increases, leaf area expands, and the plants become thin and weak, making them very prone to lodging. After lodging, the plants overlap and shade each other. After a few days, the leaves turn yellow and the plants rot, causing Chinese chives to become waterlogged and die, resulting in missing plants and broken rows. Therefore, when growing Chinese chives in summer, it is essential to focus on controlling excessive growth and promoting sturdy growth, and to base fertilization mainly on phosphorus and potassium fertilizer, increasing stem thickness and improving strength, achieving sturdy but not excessive growth, with thick roots and strong seedlings.
3. Remove flower stalks in time
Late summer is the period when Chinese chives bolt and set seed. Bolting and seed setting in Chinese chives consumes a large amount of nutrients. Under normal circumstances, Chinese chives that bolt and set seed are reduced by about 20%-30% compared with those that do not bolt and set seed. Therefore, when Chinese chives bolt in late summer, remove the chive stalks in time, so that nutrients are not excessively consumed. If the chive stalks truly cannot be removed in time, then before flowering, use a wooden stick to break the chive stalks below the chive flowers, to reduce nutrient consumption as much as possible.
4. Control chive maggots
Chive maggots are the most important insect pest in the process of Chinese chive production, and they often cause large-scale total crop failure of Chinese chives, so preventing and controlling chive maggots is also a key task in Chinese chive cultivation. Under normal circumstances, spring and autumn are periods of high incidence of chive maggots. After removing the shed, promptly use 48% chlorpyrifos emulsifiable concentrate, 1 kg per mu, and water the roots to control them. Before covering the shed, use it again, using 48% chlorpyrifos emulsifiable concentrate, 1 kg per mu, diluted with water and poured at the roots for control, with relatively good results.
