Planting time and method of leek

The planting time of leek can be planted all the year round, but it is better in spring and autumn. Leek planting method: select the land close to the water source and highly fertile, and use the transplanting method. Three seedlings can be planted in each hole, and each plant spacing is 15-20cm. About 7 days after planting, urea can be mixed with water to fertilize. In the later stage, livestock feces, human feces and urine water and urea can be used for topdressing, and pesticides can be sprayed regularly in the growth process of leek to control diseases and insect pests.

First, planting time

1. Leek can be planted in spring, autumn and winter, but it can also be planted in summer, but the temperature in summer is too high, which will lead to low survival rate, quality and yield.

2. The more suitable seasons for planting are spring and autumn, in which Chinese chives grow vigorously, grow big and tender, and have better quality and yield.

II. Site selection

Leek has a strong ability to adapt to the land, and it is more suitable to be planted in plots close to water sources, strong water storage capacity and high degree of fertility. this kind of soil has a strong ability to reproduce leek, and the color and luster of leek will look much better.

3. Planting

1. There are two ways of planting leek. Chives can be reproduced sexually or asexually. Sexual reproduction is to sow and raise seedlings in rows of selected seeds in a good plot of land. But this method is rarely used in life.

2. Leek is commonly used for transplanting, that is, asexual reproduction, during which good leek seedlings will be purchased and planted at appropriate intervals, generally 3 seedlings can be planted per hole.

IV. Density

1. The reproductive ability of leek is relatively strong. Basically, after planting and surviving, after waiting for about 7 days, you will see that several new leek seedlings will emerge around the original 3 leek seedling holes.

2, and leek will continue to multiply, if not harvested in time, it will grow densely over the whole plot, but the growth is relatively thin, not very sturdy, so the suitable interval for each plant is about 15-20cm, and the interval for each row is about 25-30cm.

5. Fertilization

The main results are as follows: 1. First, we should apply sufficient basic fertilizer, and then, about 7 days after planting, urea can be mixed with water to irrigate leek, which is beneficial to promote the robust growth of leek seedling.

2. After each harvest, topdressing should be carried out according to the growth of leeks and the fertility of the soil in the field. Generally, manure of livestock, human feces and urea can be used for topdressing.

VI. Disease prevention

1. After the leek is planted and survived, it is necessary to spray pesticides regularly to the leek. Generally, there will be some worms that eat leaves, or the phenomenon of premature senility caused by malnutrition caused by lack of water and nutrients in the field.

2. Therefore, the growth of leeks should be observed at any time, and when diseases and insect pests are found, pesticides should be sprayed in time for prevention and control. Generally, pesticides can not be sprayed within 15 days before harvest, if spraying pesticides will affect the quality of leeks.
