Organic fertilizer, inorganic fertilizer and liquid fertilizer can be used to grow leeks.

1. Organic fertilizer

Organic fertilizer includes animal manure, green manure, cake fertilizer and other fertilizers, which can ensure the looseness and drainage of the planted soil and make the leek roots grow better. However, organic fertilizer needs to be used after it is decomposed, so as to avoid bacteria in the fertilizer and affect the growth of leeks.

2. Inorganic fertilizer

Inorganic fertilizer is a chemical fertilizer rich in trace elements such as nitrogen, phosphorus, potassium and calcium. In the process of cultivating leek, it can provide nitrogen fertilizer as the main fertilizer, supplemented by phosphorus and potassium fertilizer, and improve the growth rate of plants.

3. Liquid fertilizer

Liquid fertilizer is the fertilizer obtained by sealed fermentation of rice washing water and orange peel water. This kind of fertilizer is acidic, which can adjust the acid-base ratio of soil and provide a suitable soil environment for leeks to grow.

planting skills of Chinese chives

When planting Chinese chives, sandy loam or clay loam that has not been planted with onion and garlic vegetables for nearly 1-2 years should be selected. In order to prevent Chinese chives from maggots, 2kg of 5% phoxim granules per mu can be evenly spread with 7-1m-15kg of dry fine soil. After shallow tillage, it should be raked and leveled to form a border with a width of 1.2-15 kg.

after soaking leek seeds to accelerate germination, sow them in the seedling bed by wet sowing method, and cover the soil twice, the first time with a thin layer of soil, and then cover the soil for the second time after moisture regain. The total thickness of the soil is 2cm, and the amount of seeds used per mu is 6-8kg. After covering the soil, cover the plastic film to increase temperature and preserve moisture.

lightly water leek seedlings about 5cm high, and loosen the soil in time. After 1cm, you can apply decomposed manure or topdressing urea 2-3 times in combination with watering, and apply .5-1kg of crystal trichlorfon per mu with water to kill leek maggots and other pests.
