How do you grow leeks? What is the seed price and planting method? Experienced people do this.

Leek is a kind of perennial herbal vegetable, which can be picked and cut every once in a while, which is very popular, so how should farmers grow leek? What is the seed price and planting method?

The seed price of Chinese chive

The price of leek seeds is about 80,150 yuan per jin, which varies according to the quality, variety, origin and market of the seeds. Leek is very adaptable, cold-resistant and heat-resistant. It is cultivated everywhere in our country and can be produced year-round in many areas in the south. Although the aboveground part of the north is dead and the underground part goes into dormancy in winter, it will continue to germinate and grow after the topsoil is thawed in spring. Multi-purpose seed reproduction and plant propagation.

Second, how to grow leeks? What is the planting method?

1. Planting time

Leek likes the cool climate, and the most suitable temperature for seed germination is 15 to 25 degrees, so it is mostly planted in spring and autumn, sowing in April and the end of August and early September in the north, and from March to April and September to October in the south. At this time, the sowing seedlings come out quickly and evenly, and it is not easy to get sick.

2. Main points of sowing

Leek is a perennial vegetable, so in order to lay a high yield foundation, we must apply sufficient base fertilizer before sowing, but the fertilizer must be fermented well, otherwise it is easy to cause diseases and insect pests. The sowing depth should generally be controlled within 2 centimeters, and the sowing must be suitable for density, so that the yield will be higher, and the soil surface should be watered thoroughly after sowing, and the whole seedling can be produced in about 15 days when you see the soil surface dry before emergence.

3. Daily management

The daily management of leek is relatively simple, basically only weeding and watering can be done, but if you want it to grow fast and strong, the fertilizer must keep up with it. When leek grows to a height of more than 10 centimeters, you can pursue fertilizer at this time. Nitrogen fertilizer is the main fertilizer. I recommend soaking and fermenting with sesame oil residue, mixed with water into the leek field when watering, which can not only make the leek grow fast, but also taste very strong. Topdressing is the key to the growth and firmness of leeks every time they are watered, and every time they are cut.

4. Main points of harvest

Although leek is harvested by stubble, its harvest interval must be paid attention to, generally not less than one month. If the interval is too short, it is tantamount to killing the goose that lays the golden eggs. And the last crop of leeks in autumn, that is, 20 days before the frost, should stop harvesting leeks to prepare for their winter dormancy.

Finally, many people ask themselves that the leeks they grow are always yellow leaves, what should they do? In fact, the yellow leaves of leeks are also for many reasons:

► is deficient in trace elements. Leeks with yellow leaves are generally not sprayed or sprayed with trace elements such as iron, copper and zinc, and yellow leaves are formed due to the lack of such elements.

Due to the partial application of nitrogen fertilizer to ►, the proportion of nitrogen, phosphorus and potassium was out of balance, which inhibited the absorption and utilization of trace elements and formed yellow leaves.

Excessive application of humic acid fertilizer in ► changed the physical and chemical properties of soil and showed acidification, which was not conducive to root development and growth, nutrient absorption and transformation was not smooth, and leaves turned yellow due to malnutrition.

► only pays attention to the application of chemical fertilizer and neglects organic fertilizer, resulting in reduced soil porosity, poor permeability and poor root respiration, resulting in malnutrition and yellow leaves.

► watering blindly caused excessive humidity in the field, which affected root respiration and nutrient absorption, resulting in yellow leaves.

► disease and insect damage, especially after the damage of leek maggot, the root absorption capacity decreased, the nutrient supply of leaves was insufficient, and withered and died in serious cases.

Therefore, we should take preventive measures as soon as possible.
