What clever trick does leek use fat to have? What are the points for attention in summer planting?

Leek belongs to perennial root vegetables of Liliaceae. It is highly adaptable, cold-resistant and heat-resistant. It is cultivated all over China. What are the tricks for leeks to use fat? What are the points for attention in summer planting? Let's take a look at it together.

First, what is the best way to use leek fat?

Grow leek at home, you can apply fully mature organic fertilizer in March and June every year, organic fertilizer contains a lot of nitrogen, can make leek thrive. Leek is different from other plants, it can be harvested when it grows to a certain height, and the cut leek can grow again under sufficient water and nutrients, so in order to provide sufficient water and nutrients to leek, topdressing and irrigation can be done 3-4 days after harvest.

Topdressing is mainly nitrogen fertilizer, and an appropriate amount of feces and urine can be added, which can be applied with water, or ditched first and then watered. After harvest, topdressing must wait for the harvest wound to heal before watering and fertilizing, otherwise it is easy to cause wound decay and fertilizer damage. If the flowers with feces and urine are applied, they should be diluted in advance and fully mature, otherwise they are prone to insect pests. The leek should be harvested, watered and fertilized once, so that the new leek is as thick and green as the first crop of leek.

Chives grow leek flowers in summer, so the application of phosphorus and potassium fertilizer before the flowering stage of leeks can promote the flowering of leeks. It can also meet the demand of phosphorus and potassium fertilizer for leek flowers by applying common plant ash in rural areas, and plant ash can also prevent the occurrence of leek diseases and insect pests.

Leek is not resistant to waterlogging, and it is easy to have rotten roots in the soil with stagnant water for a long time, so it should be drained in time in the rainy season and watered in time in the dry season, so that the leek can grow healthily in a good growth environment.

II. Matters needing attention in summer planting of leek

1. Free of cutting

The high temperature in summer leads to less nutrient accumulation and high consumption, which affects the plant growth, and the leaf tissue fiber increases, the texture is rough, and the growth weakens. Harvesting should be stopped from late June to early August to facilitate root maintenance.

It can be harvested 1-2 times from August to September, stop harvesting after late September, and the last harvest should be slightly higher. In particular, the leek planted the year before last stopped harvesting during the high temperature in summer, and sprinkled water with a spray pot every morning and evening to keep the surface moist, but not splashed.

2. Weeding

Summer high temperature, rainy, weed breeding, affecting the growth of leek, farmers should pull up the weeds in time.

3. Topdressing

Attention should be paid to the application of microbial fertilizer such as gold, because in the season of high temperature and drought, the mesophyll tissue of leek is rough, the quality becomes inferior and the edible value is low, so the harvest should be stopped and the leek should be fertilized in time to prepare for autumn production. Topdressing should apply fully mature chicken manure, preferably a good quality bio-organic fertilizer, such as golden rooster manure fermentation organic fertilizer is a good starter for fermenting mature chicken manure. The utility model has the advantages of fast fermentation, good fermentation, high temperature fermentation and low temperature fermentation, which greatly shortens the production time and reduces the cost.

4. Bolting

As the flowering and knot of leek needs to consume a lot of nutrients in real time, in addition to picking the field, the leek should be removed in time when the leek is young and high-yielding plants should be cultivated.

5. Control Fusarium wilt

Chinese chives are prone to Fusarium wilt in summer high temperature season, especially after heavy rain, when exposed to the hot sun, the disease occurs near the ground, and the whole plant dies when it is serious. Therefore, in summer management, attention should be paid to drainage and waterlogging, and yellow leaves should be removed to maintain good ventilation between rows.

6. Prevent lodging.

Due to cutting-free, sufficient fat and water, vigorous growth and other favorable factors, leek often lodging in summer, after lodging, it is easy to rot, and induce epidemic disease, resulting in death. Therefore, farmers need to take timely measures to prevent lodging, such as not excessive application of nitrogen fertilizer, pouring the right amount of water to chives, frequently preventing waterlogging in case of heavy rain, and cutting short leek leaves when lodging may occur when leek leaves are too long, which are all good ways to prevent lodging.

In the hot and humid season of summer, we need to do a good job in the management of leeks, safely through the dangerous period, and effectively improve the quality and yield of leeks.
