How to plant green beans? The green beans are actually the cowpeas we usually talk about. Generally speaking, they can be planted and cultivated in the spring and autumn, and all kinds of green beans are planted in the north and south of China. Let's learn how the delicious green beans are grown together.

First, soil selection

The requirements for soil in cowpea planting are actually not high. Loam and sand can be used as long as irrigation and drainage are good. Of course, the more fertile the soil is, the higher the yield is.

Second, the variety selection

If we plant cowpeas in early spring, we generally choose high-quality varieties with high disease resistance, high yield and strong cold resistance.

Third, seedling technology, seedling management

The cold resistance of the green beans is good, so it does not need high temperature. In many areas, the greenhouse seedlings are transplanted. Note that when the temperature is higher than 25 degrees, it will affect the differentiation of the bean sprouts.

Seedling time

Small shed planting can be planted around the spring.

2. The whole car

Firstly, the seedbed is made thin, and the carcass is 1.2 meters wide and 20 cm deep. The length of the car can be determined according to the amount of seeding. Pour the bottom of the water, then smooth the surface with a sand board, use a nylon rope to make a 9 cm wide line, then cut into a 9 cm × 9 cm square with a knife, pick a 1-2 in the middle of the square with a knife A centimeter deep nest.

3. Sowing

1 seedling

Seed 4 seeds in a square nest and cover with a fine soil. Fields with underground pests can use 1000 times solution of phoxim when watering. After doing a good job, lay a layer of mulch on the top and cover the shed. After the seedlings break the soil, the mulch can be removed. If there is a sun, the shed can be uncovered. When the seedlings grow to 2 true leaves, they can be planted in the shed (no sheds, only the mulch can be planted and transplanted 10 days later).

2 live broadcast

Green beans can also be broadcast live in Daejeon, but planting time should be postponed until February 25. The fertile field will be opened 1.4 meters, according to the nest distance of 35 cm -40 cm, two lines per pod (20 cm from the side of the box), 4 seeds per nest, and then covered with dirt. After the sowing, the mulch film is laid on the top, and the mud is pressed around. After the seedlings are unearthed, the seedlings are smashed to the mouth and the seedlings are taken out. If the soil is dry, you can first dig the nest, pour the water, and then sow the seeds before they are dried.

Fourth, field finishing, fertilization

Daejeon finishing

1 Weeding: Grass-heavy fields can be manually weeded or chemically weeded. Chemical weeding can be carried out with herbicides such as Roundup and Gram, and sprayed in the open space after the harvest, 25-30 kg per 667 m2 of water. The whole box can be ploughed in 7 days.

2 Soil disinfection: The field with more diseases can be spread with 3-5 grams of dermatophyte or 100 kilograms of lime per 667 m2 for 1 square meter, and then ploughed and mixed.

3 Pests: Fields with more soil pests can be applied by phoxim mixed soil.

2. Fertilization

The base fertilizer can be applied at one time, and no top dressing can be added in the future, which saves labor and time and has good effects. The specific fertilization formula is as follows, and one can be selected according to the actual situation:

1667m2 septic ripe manure manure 3,000 kg, phosphate fertilizer 50 kg, potassium fertilizer 25 kg, urea 10 kg.

2,667 m2 of fermented farmyard fertilizer is 1,000 kilograms, 100 kilograms of decomposed oil, 50 kilograms of phosphate fertilizer, and 10 kilograms of urea.

3667m2 cast chicken, duck manure 3,000 kg, phosphate fertilizer 50 kg, potassium fertilizer 20 kg.

3. Open the car

After the fertilizer is evenly applied to the field, the tractor is used or the cattle are ploughed, the fertilizer is evenly mixed into the soil, and then the whole car is placed. The small shed is planted in a general 1.5 m (groove), and the ditch is 20 cm deep.

5. Transplanting and post-plant management

Transplanting

Before transplanting, first digging the nest on the finished car, two rows per car (the center of the nest is 25 cm from the side of the car), and the nest is 35 cm - 40 cm. When transplanting, the surface of the square seedlings should be parallel to the carcass. Pour the root water, lay the mulch and lead the seedlings. Then pour a small amount of water on the mulch and cover the shed. (The length of the bamboo in the small shed is equal to the width of the film. The width of the bamboo is 2 cm, which is more suitable. Insert one piece at a distance of 1.5 meters.)

2. Scaffolding

When the green beans are generally as long as 20 cm, they can be framed. Each nest should be covered with a shelf (the shelf should be no less than 2.5 meters), and the middle frame should be fixed with a crossbar.

Sixth, harvest

It should be harvested when the bean pods are rounded and rounded, and the tender harvesting affects the yield, and the late harvesting reduces the quality. The above is the cultivation technique of green beans, you can collect spare å“Ÿ!

The above is the cultivation technique of green beans. Look at the friends of the vegetable farmers. What do you think are needed to be added? I hope everyone can achieve high yield in the future planting process!
