High production techniques for the 1st autumn
Autumn high-yielding cultivation
1. Characteristics and markets of autumn
Autumn, a nutritious vegetable, has gained prominence on the market in recent years. The autumn contains a variety of nutrients that meet the requirements of a healthy diet and growing areas. How to achieve its high productivity is an urgent need for many growers. This paper will provide you with a detailed description of the high-yielding planting techniques of the autumn autumn, each of which is essential, ranging from ground selection, seeding to field management, pest control. The technology will help you to harvest all the sunflowers easily and efficiently。
Autumn, a vegetable known as a nutritional treasure, is not only unique in taste, but also rich in various nutrients, such as proteins, gums and sugar. It originated in the north-eastern part of africa and is now widely cultivated globally, especially in japan, the united states and my country, taiwan and hong kong, where it once became a new pet on the table. In recent years, along with the quest for healthy diets, the area of autumn cultivation has been expanding, especially in the south and south of the sea in winter, and has become representative of green vegetables. Their flowers are fully flowered and open from the bottom up, either through self-plowing or through insect pollination. In the guangzhou region, after years of displaying the practice of growing new varieties of vegetables, we have developed an effective planting technique aimed at helping more growers to achieve high-yield cultivation of sunflower。
2. Caste selection and breeding
In selecting the acorn seeds, emphasis should be placed on their quality, growth and adaptability, taking into account the recognition of the audience in the market. The selection of good varieties and the subsequent leaching of warm soup and seedlings have led to successful breeding of seedlings. The ideal seeds should have such characteristics as green and bright skin, green and long-lasting flowers, such as pentagrams, qingfu, and four seasons of green sunflowers, which are good options。
In guangzhou, the suitable planting period for yellow autumn is from march to august. Before seeding, it is recommended to use a diet or seedling, together with a professional seedling base. First, the seeds are immersed in warm soup, which is thoroughly washed after six to eight hours. Thereafter, the treated seeds are sprung in an environment ranging from 24 to 28°c, and in about 24 hours the seeds should start to move and appear white. At this point, seeds can be sowed into trophic spores or dens, with only one seed of whited seed per den being contained at a depth of about 1. 5 cm. If the seed is not white, then two particles are cast in each den, and a strong seedling is selected before the leaves are fully displayed. During this period, care must be taken to regulate the temperature and humidity and to spray two to three times 1,500 times the bright shield or 1,000 times the zinc solution in order to prevent seedling root and sudden fallout. At the same time, the water is combined with 300 times the glucose roots of the village every 7 to 10 days. When a seedling reaches the age of approximately 25 days and grows up to four to five leaves, a week of seedling can be transferred to daejeon。
3. Land consolidation and planting
In order to ensure the healthy growth of the acorns, adequate soil preparation is required for several months of crop life. In the field as a whole, the basis for high production is laid through the application of appropriate planting patterns through fertilization and ground cleaning. It is recommended that 800 to 1,000 kg of cureochemical or organic fertilizer be applied per acre, and 50 to 100 kg of calcium per phosphate. In order to facilitate field management and harvesting, single- or double-line planting is usually used. The width of the gutter riser is set at 70 to 80 centimetres or 120 to 130 centimetres, respectively, which facilitates drainage and ventilation. In the early spring, the addition of silver ash membranes not only helps to increase the temperature of the earth, but also effectively reduces the abuse of weeds and aphids. At the time of planting, the range should be between 45 and 50 centimetres, while the two-line planting should be based on a font layout to maximize the use of sunlight. Select to plant it in the middle of the sun or at noon, and ensure that the water takes root to stabilize the seedlings。
4. Field management
Field management is an essential link throughout the whole autumn growth cycle. Management methods such as ploughing land, fertilizing irrigation and foliage processing have increased the production of sunflower. This includes regular monitoring of soil moisture and fertility, as well as timely irrigation and fertilization. There is also a need for regular weeding and pine soil in order to maintain a balance of the air flow and humidity of the soil. Care should also be taken to combat pests and diseases and to detect them in a timely manner and take effective measures to address them. Through scientific field management, the healthy growth of the autumn can be ensured, resulting in improved yields and quality。
4. 1 cultivation of grass and earth
In the sapling season of the autumn, slow growth and relatively weak growth make it necessary to perform farming and weeding in due course. In the middle and late stages, as plant growth accelerates and the area of leaves rises, in order to prevent them from falling, every heavy rain should be followed by fatting and timely cultivation of the soil to protect the root system。
4. 2 fertilizer water management
The whole life of the autumn is nourished by water over a long period of time, and the soil should maintain moderate humidity and sufficient oxygen content to facilitate the growth of the root system for absorption and flowering. In heavy-rained weather, attention should be paid to the timely drainage and prevention of root causes. In the four to five days after the plant has been replanted, a seedling is to be followed up to promote fattening, with 200 times more urea and 1-2% of imported urea solution in norway. After fertilization, the plant is washed with water in time to prevent fertilizer burns. Before flowering, heavy fertilization should be pursued again and combined with irrigation. It is then followed by fattening every 10 to 15 days, mainly with a three-dollar balance of compound fat。
4. 3 processing of leaves in due course
In order to ensure that the acorn focuses on flowering and avoid excessive growth, we can use a leaf twist. In particular, it is to bend the leaves gently and down, so that nutrition growth can be effectively regulated. At the same time, there is a need to erase the new sprouts and ensure that the principal is the main force for results. When the plant enters the later stages of growth, the old yellow leaves that appear in the lower layer should be cut off in time。
5. Pest control
The main disease that acupunctures may face in their growth is the flower virus, which not only endangers leaves but also the quality of the fruit. Rational use of biological and chemical means of control to control the spread of pests and viral diseases. In the event of infection, it not only destroys the photocosynthesis of the blades, but also leads to poor appearances of fruit, which in turn affects market acceptance. From the start of the sapling season, comprehensive measures of prevention are needed. Biocombination can be carried out on cedars, or the whole plant can be sprayed regularly with high-efficiency solutions such as chlorocypermethrin, aphids, thorone and ayrex。
6. Collection methods
It usually takes about 60 days from seeding to the first harvest. When the flower is abated and after a maturity period of 5 to 7 days, its length reaches 7 to 10 cm, it is the best time to harvest. The timing of harvests is based on the growth cycle in order to achieve the dual guarantee of high productivity and quality. During the harvest, scissors must be used to cut the base of the handle to ensure that the plant is not damaged。
