In areas where rainfall is more abundant, the majority of the population cultivates cabbage by digging trenches and building higher fields. Vegetables are grown in the form of deep trenches and are more easily drained from the fields。
Vegetables are planted in more moist soils, with a consumption of 1,300 kg of livestock excreta. For earlier-maturity vegetable varieties, bottom fertilizers are applied to faster rapid-effect ammonia。
For the later-maturity variety, more nutrients are needed throughout the growth and development process. The soil is mixed with phosphorus, potassium and school fat, which are applied to the floor。
Each acre of land is used for the application of manure at 3,200 kg and is mixed with 18 kg of calcium phosphate and 55 kg of grass-wood ash。
Over the long term, more moisture is required。
However, care must also be taken to water the water and water in the ditches of the field. When the water is high above the surface of the field, the spill is drained to avoid spilling the root lines of the bubbling vegetable。
Plantation at 01
1 plows
Three rows of ploughing are to be made on a 1. 5-metre wide field, where different varieties of vegetable vegetables are to be planted at maturity. Early-maturity vegetable varieties require 2400 plants per acre plot. A variety of 1,700 plants per acre of land is planted in mid- and late-maturity。
The share of nitrogen fertilizer is higher throughout the growing and developing of the cabbage. The application of phosphorus and potassium fertilizer is increased by the end of the ball period, with manure fertilizer at 1400 kg per acre and ammonium sulphate at 9 kg。
Article 2, beam leaf
When the part of the broccoli formed in the middle is exposed, the leaves outside the cabbage are tied to the planted garden with a straw rope. Tied leaves are better able to wrap up the center of the plume so that the plume is not subject to direct light。
The third is shiba
When the seedlings break out of the soil seven days after the soil is removed, the seedlings, which are overgrowing, are artificially combed to keep the plant at a distance of four centimetres。
Half a month after the seedlings have grown the soil, it is necessary to use a fake planting method to keep the lined plant between eight and nine centimetres. There is also a veil to shield the vase from strong light, which can be watered during fake planting。
02 water fertilisation and disease control
Its 1st, water fattening
Temperatures are also rising after april, and during the planting of cabbage, vents are to be opened to reduce temperatures in the gardens. Control of water and fertilizers after slow seeding and, to some extent, intervention in vegetable management。
The application of compound fat on each acre plot is 2 kg and 7 kg of urea is added, allowing the florist to grow even more abundantly。
During the first half of the month before the buds grow, the vegetable is sprayed three to four times with a 15% water soluble boron fat 1,200 times the water solution. There is no need for any additional watering of the cabbage in the early part of the period when it is growing in a low-temperature environment。
After the temperature has returned, the vegetable must be watered in small quantities during the midday period. During the time when a flower ball is formed, the soil should not be over-watered。
2, viral diseases
When the cuisine is infected with a viral disease, there are round brown spots on the leaves, which are accompanied by visible foliage characteristics. On the leaves of later cuisine, there will be black and brown dry spots, which will make the leaves look like a wrinkled expression after being immersed with boiling water。
Infected plants are slow to grow and produce particularly small flowers. When infected with viral diseases, leaves are deformed and shrinked to keep the strain small and with time, it gradually dies。
3 - prevention and control management
Putting seeds in an 80-degree environment for dry thermal treatment will eliminate the virus carried by the seeds in two days. There is also a need to adjust the layout of well-planted plots, using scientifically sound planting methods and shifting cultivation to different crop varieties. It should not be a pity to remove and burn in a timely manner in the event of infestation with this type of viral disease。
Do not prolong the time spent in acupuncture, and use 10 to 15 days for acupuncture. At the beginning of a viral disease in the cabbage, can we plant a fungus spray and a prick water agent? Plants are sprayed every 10 to 12 days, and three consecutive sessions are required to contain the spread of viral diseases。
Infection of cyanosis seriously endangers the yield of the plant, leading to symptoms of disease in leaves and plumes, and in the troughs. It will also appear on the leaves, with yellow stripes accompanied by black and brown molds。
When the disease is more serious, the corrosive point is mixed with grey and white cortex, leading to the dry atrophy of leaves. At high temperatures, the leaves will have a white cortex of frost。
Forty per cent of the methaqualone powder and seeds will be fully sterilized by delayed planting during periods of less rain. When the disease begins to appear in the field, the plant can be sprayed with a 400-fold water solution of ethyl phosphorus aluminum and a 75-per-cent 100-per-cent water solution of humid powder。
