How do you plant a round leaf to curb blue vegetables? Artificial planting technique of round leaf blue cabbage

February 28, 2023

The blue cabbage is also known as the bitter mustard, which is a kind of wild vegetable. Its seeds and whole plants can be used for medicinal purposes. Among them, the round leaf blue cabbage has a high selenium content and can be used for treating Keshan disease, Kashin-Beck disease and the like. Blue cabbage is distributed throughout China.

Blue cabbage is mainly grown on hillsides, grasslands and fields. With the diversification of people's food sources, the pollution-free blue cabbage has become a new favorite of people and boarded the table. The blue cabbage can be used in addition to being edible. Industrial production. Therefore, the cultivation of blue cabbage is of high value. The planting techniques of the round leaf blue cabbage are now shared as follows:

First, soil preparation and fertilization

The round leaf blue cabbage is suitable for the soil with high selenium and is cultivated and grown very rich in selenium-enriched soil. The requirements for the natural environment and soil conditions are relatively harsh, and low-cold paddy fields are not suitable for cultivation.

Fine land preparation

When the blue cabbage is emerged, the ability of the cotyledon to excavate the soil is weak. If the soil is compacted and sloppy, it is easy to cause seedlings and lack of seedlings and ridges. The main roots are underdeveloped, with shallow roots and many lateral roots. Therefore, before sowing, the soil should be finely ground, the depth of the cultivated land is about 20 cm, the tillage is fine and flat, and the deep tillage is combined with the application of organic fertilizer. Each 667 m 2 is applied with 2500~3000 kg of high-quality decomposed organic fertilizer and 20~25 kg of ternary compound fertilizer.

2. Selection

Choose before breeding. Removal of grains and impurities, selection of full-grain seeds for seeding and drying, is an important measure to improve seed vigor, enhance germination potential, and ensure seedlings are strong.

Second, sowing

When the soil texture is loose and the moisture is poor, it can be soaked deep, and gently suppressed after sowing; when the soil is heavy or the soil moisture is large, it can be broadcast lightly. If the soil is corroded after the sowing, it should be loosened in time to facilitate emergence. Because of the strong drought resistance of blue-sucking vegetables, it is not easy to plant in low-injection paddy fields.

The blue-sucking seeds are very small, so that they can be evenly planted with sand in order to ensure uniform seeding. In the shallow ditch with a line spacing of 15 cm and a depth of 1.5 cm, cover the soil and suppress it. The cover type should not be very thick. Otherwise, the seedlings are not good. Generally, the soil cover is 1~1.5 cm. It can be emerged 5 to 7 days after sowing.

Third, field management

Intercropping

When the seedlings are 6~8 cm high, the seedlings and seedlings should be timely carried out, and the lack of seedlings and loosening of the soil should be done.

2. Fertilizing and watering

Irrid once in mid-April and carried out manure and manure. Generally chasing high-quality decomposed organic fertilizer 500~750 kg, combined with watering, pouring 10~15 kg of compound fertilizer with water.

Fourth, seed breeding

Seed reproduction can be divided into seed direct seeding and seedling transplanting, among which seedling transplanting is easier to obtain high yield and achieve better benefits.

1. Selection and germination

Seeds with full grain and mature germination rate of more than 85%. Soak the seeds in warm water at 40 °C for 24 hours before sowing, then remove them, mix them in 1:1 wet sand, germination at 20~25 °C, and keep them moist once a day, until the seed rupture rate reaches About 30% can be planted.

2. Selection and sowing

(1) The root system of the blue-sucking vegetables is developed, and the soil requirements are not strict. Generally, it can grow well at pH 5~7.5, but the sandy soil with loose soil and fertile soil, deep soil and good drainage is better.

(2) Seeding and seedling cultivation in the south is mainly for winter sowing, and spring sowing; in the north, it is mainly spring sowing, and planting with facilities can also be planted in advance. The south will be planted in late March and the north will be planted in early May. 5 to 6 days before sowing or transplanting, 20 cm deep, combined with 667 m 2 of cultivating manure, 3500~4000 kg of manure, 50 kg of grass ash as base fertilizer; breaking the clods to open the ditch, making it into 1 ~1.4 m wide ridges, according to the row spacing of 50 cm, plant spacing 25 cm open points, 2 ~ 3 capsules per hole, covering soil 2 cm compaction, watering. The ground temperature is suitable for emergence in about 7 days, and the seedlings should be inferior when they leave three true leaves.

3. Management measures

(1) Miao Miao

During the seedling period, weeding and soil should be carried out in time to prevent the lush seedlings on the ground from falling during the rainy season, resulting in poor ventilation and light transmission, which is prone to disease.

(2) top dressing

When the height of the seedling is 10 cm or more, the thin manure is applied once, and about 1500 kg per 667 m 2 is applied. The second time is in the middle of July, and the manure is about 200 kg per 667 m 2 , the third time is 8 In the second half of the month, 25 kg of phosphorus, potassium and compound fertilizer per 667 m 2 will increase production.

4. Timely transplanting

It can be transplanted from February to August. In order to extend the harvesting period, most of the high-yield cultivation is carried out in early February. The cultivation with plastic film mulching can be carried out as early as January 20th. When transplanting, the root system should be damaged as little as possible, and the size of the seedlings should be fixed and planted. Generally, 2 seedlings per plant will be planted, and 3 plants will be planted in each hole. When planting, the surface will be flattened, and then 5% of the thin manure will be used. Drain the root water. Transplanting should be avoided when the hot sun is at noon to facilitate survival.

5. Harvesting and processing

It can be harvested after planting for more than 2 years. In August, during the flowering season, flowers can be picked and dried in a pot. After seeing the main stem change from green to purple in September, the whole grass can be harvested when the seeds are full, and the impurities are removed to dry.

The therapeutic value and medicinal value of the round-leaf blue-sucking vegetables are high. Planting blue-sucking vegetables is one of the projects of the majority of farmers to get rid of poverty.
