They are a type of cabbage with smaller head than ordinary cabbage, with shorter growth cycles and generally ready to be marketed for about 45 days because of their particularly short growth cycles, which are also more efficient. The following is a description of the techniques used to grow doll vegetables。
1. Botanical properties
(1) form characteristics
At the beginning, there were two leaves, which later became a cross, slowly beginning to grow more new leaves from the centre, and gradually as the central part of the growth of the leaves began to gather together, and the pellets formed columns, with almost the same size, up and down. Commodity balls can reach an altitude of 20 centimetres, with a diameter of about 8-9 centimetres and a netting weight of about 150-200 grams。
(2) growing environment
(b) the suitable temperature for the growth of the doll food is 5 °c-25 °c, and when it is below 5 °c, it is prone to freezing, resulting in loose or uncapable carrying of the plant; the virus is easily infected at above 25°c. At present, child food can be cultivated in the north and south of the country, mainly in the provinces of shandong, hebei, yunnan, guangdong and fujian。
Breeding techniques
They are usually seeded to breed, and do not look at their seeds very small, but have a very high rate of survival. So when's the right time to sow?
(1) sowing time
They can be sowed on the occasion of the anniversary, but specific decisions are taken according to local temperature conditions. The planting time is usually measured by temperature stabilization between 10 and 28 degrees celsius。
(2) land selection
The baby food prefers to live in fertile and loose ground, where the land is chosen for deep-spreading, and where the conditions are favourable to the construction of spray facilities for timely recharge. When the land is ready, the ditch must be opened, with simple and convenient hooks or hoes, and when the ditch is ready to sow。
(3) sowing methods
The seeding method is to spread the seeds directly into a ditch and, because the seeds are very small, they must be operated with great care, usually at a rate of 0. 5 kg per acre, and then spread the seeds into the gutter and then into the gutter with a composite fertilizer ready for growth, at a rate of 30 kg per acre. The soil is then covered with seeds and fertilizers, and water is finally sprayed again, not only to maintain the humidity of the environment in which the dolls grow, but also to promote seed gerries. In about three days, the saplings will come out of the ground and then enter the field management phase。
3. Field management
Since the growth cycle of doll foods is about 45 days long, in order for the plant to grow into good vegetables, it is necessary to provide them with the most sophisticated care in this short period of time, in particular in the field management phase:
(1) spraying
During their growing up, dolls are often watered in order to keep their fields humid and must not be left without water. During the long term, water is sprayed every day, the most suitable method of watering bellies, which is to ensure the distribution of water, maintain the wetness of the ground and have good control over the amount of water, so that the bellies can be absorbed evenly to the appropriate amount of water. It is best to choose between 8 and 10 a. M. And between 4 and 6 p. M. Each morning, with a spray of about an hour or so。
(2) first seedlings
After about 10 days of growth, a seedling is given to the doll food, also known as the sapling, by which it is reduced to provide sufficient space for the growth and development of the baby food, since too dense a plant can lead to the growth of the strains, causing ill-health and disease and naturally affecting the decline in products and quality. In general, it is sufficient to limit the distance between plants to about 7-8 cm. In the meantime, weeds can be removed。
(3) first time chasing fat
This fat hunt can provide sufficient nutrients for the growth and development of the doll food, and the fertilizer can be selected for compound fertilizer, which can be distributed directly around the doll food, at a rate of around 40 kg per acre. Water must be sprayed immediately after fertilization, in order to accelerate the dissolution of compound fertilizer to help digestion and absorption, at a time of approximately 30 minutes。
In about three days' time, additional leaf-leaf fatting could be added, with the choice of high-efficiency exclusive leaf-leaf fatting, at a level of 3 kg per 5 gram of water, so that the solution could be distributed directly on the blade, preferably between 3 p. M. And 5 p. M., and the amount of fattening had been used as the standard。
(4) cultivation
When the baby food grows for about 10 days, it is only possible to carry out a cropping exercise, which will ease the surface of the soil with a small beech head. This will facilitate the growth of the root system, which must be carried out in a careful manner and must not harm the root line of the baby's food。
(5) first pest control
There are very few pests and pests in doll foods, mainly on a preventive basis. During this period, a pest prevention exercise was conducted to prevent infestation by pests and fungi, with the option of spraying with a 2,000-principal aphrodisiac, and the application of evenly distributed fluids on leaves. In general, it is preferable to choose between around 10 a. M. Or between 3 p. M. And 5 p. M. When the doll food grows around 25 days, a second seedling will take place。
(6) second seedlings
The leaves in the root of the doll are grown around them, and as the plant grows smaller and smaller, they have a direct impact on the development of the doll, so that a second seedling can be performed in time, and the distance between the doll's vegetables can normally be kept at 8-10 cm。
(7) weeding
The growth of doll vegetables is easily accompanied by the growth of weeds and crops for nutrition, so it is important that weeds be removed in time to create a good growth environment for crops。
(8) second fat chase
This time, it was called “sapling fat”, which was used as a combination of fertilizer for fatting, followed the course to the ground near the root of the plant and measured by about 15 kg per acre. Following fatting, water is sprayed immediately to accelerate the dissolution of the fertilizer and to facilitate nutrient absorption, which can take about 30 minutes. It is also important to note that the number and timing of daily water sprays will change over the period thereafter, and that normally the water spray time is best chosen between 10 a. M. And 12 p. M. And 2 p. M. To 4 p. M. Each day, so that the four hours per day will be enough to fill the water。
(9) second pest control
In the case of dolls, which are vulnerable to aphids during a period of time, prevention work is done early, with the option of spraying with 1,500 times less liquid of avil, with an even spray on the plant, usually between 9 and 11 a. M. Or between 3 and 5 p. M. Spraying must be careful and slow to take care of each part of each plant, which prevents aphids from approaching the plant。
It is also necessary to prevent folate from occurring. It can be sprayed in its entirety with 600 times less methyl-trawine, usually at 10 a. M. Or after 4 p. M. This prevention effort will enable the healthy growth of doll foods away from the disease。
With this series of management, the leaves of the dolls will gradually be held in pieces, and the harvest season will soon be over. It is important to note that water is stopped before harvest, around the 45th day of the growth cycle. It'll be two or three days before the dolls grow。
4. Collection
It is usually possible to harvest the doll food when it's tight and undisturbed, not by removing the whole group of leaves held together。
