Fertilization techniques for high yield of leek

Leek is one of the vegetables with large market demand, and the market price is stable. in addition, it is also a perennial vegetable, which can be harvested several times a year, giving farmers a lot of economic income by planting leek. But if you want leek to grow fast and well, fertilization is an extremely important work, to master the time and method of fertilization of leek is the premise of achieving high yield, then how to fertilize, let's take a look at the pro-agricultural network.

1. Apply sufficient base fertilizer

The growth of leek in seedling is less, the demand and consumption of fertility is small, and the seedling is weak, the root growth is not sound, and the absorption of fertility is weak. So at this time, in addition to applying sufficient base fertilizer, we should also apply some quick-acting chemical fertilizer to make it grow rapidly and accelerate the growth of root system. However, leek can be planted when it grows to about 20cm, and enough organic fertilizer should be applied in the planting land. After the fertilizer is sprinkled into the soil, it can be evenly mixed and leveled to make the border. After growing and maturing in the second year, it can be harvested and put on the market. At this time, it is necessary to apply fertilizer once to make the leek recover quickly and avoid premature senescence caused by nutrient loss after harvest.

2. Topdressing in time

After the planting of leek, after the hot summer, enter the cool autumn, when the temperature is the most suitable for the growth of leek, but also the most critical period of fertilizer and water management. Timely fertilization and maintaining nutrient supply is the basis for the rapid growth of leek. In addition, leek in the overwintering, depends on the accumulation of nutrients, and autumn sometimes nutrient accumulation stage, so fertilizer and water management is particularly important. During this period, it is generally necessary to topdressing 2-3 times, usually once in early September, late September and early October, and about 15 kilograms of ammonium sulfate per mu. Three days after the leek harvest, the new leaves begin to grow slowly. At this time, it is necessary to try ammonium sulfate with the same amount as before. Do not water and fertilize the leek 2-3 days after harvest to avoid root rot. Leek is not harvested in summer, summer leek fiber tissue, taste is poor, then also need to fertilize once, so that it is safe to spend the summer, the same fertilizer and dose.

3. Skillful application of plant ash

The ingenious application of some plant ash during planting can play an increasing role. In the growth stage of leek, applying some plant ash is a good water-soluble quick-acting potassium fertilizer, which can make leek root and tiller as soon as possible, and the effect of increasing yield is obvious. In addition, many leeks are planted in the greenhouse, and Botrytis cinerea is easy to occur when planting in the greenhouse, resulting in losses, and the application of plant ash can reduce the incidence of the disease. A large amount of ammonium sulfate and acid fertilizer were applied when topdressing, and the soil was acidified by long-term application, which easily led to yellow leaves and death of leek, while plant ash was an alkaline fertilizer, which could adjust the pH of soil and make leek grow normally.

The above is the high-yield fertilization technology of leek brought by pro-agricultural network. I hope it can help you. If you want to know more about leek planting, please pay attention to pro-agricultural network.
