In scallion production, people are generally accustomed to sowing in the late autumn, cutting in the spring, harvesting in the fall, and growing seasons are longer, and the harvesting season is more concentrated. Although it can be harvested at any time during the growing season of the onion, the output Lower, and poor quality. Onion season cultivation methods, autumn cuttings, harvesting and marketing in the coming summer, and autumn harvest green onions to open the supply, not only can ease the market supply on the busy season contradiction, and due to the short growing season, can be planted with other vegetables for more than a year, increase income. Onion production of 5000-6000 kilograms of green onions, only the onion acres of income up to 4000 to 5,000 yuan. Simple management, shortening of the growing season, and higher benefits are welcomed by farmers. The management points of this welsh onion cultivation are now described as follows:
Nursery
The new seeds with good seed selection and black and shiny seeds are mainly seedlings of high-leaved white or Zhangqiu scallions, with a seed weight of 1~2 kg per mu.
Seedlings were planted on the Xiangyang block, and the former fertile legume, eggplant, and fruit and vegetable plots were the best. Mushi 3000 kg of decomposed organic fertilizer, 10 to 15 kg of compound fertilizer deep-throw target, for seedling cultivation, sowing in late August.
When the seedling height is 6 to 9 cm, press 3 cm square to sparse seedlings. Seedling height 12 ~ 15 cm and 15 days before planting, each chase 1 chemical fertilizer, ammonium sulfate 10 ~ 15 kg per mu. Timely poisonous valleys are used to prevent earthworms and other underground pests, and to remove weeds. If it is found to be harmful to gray mold, downy mildew, etc., it should promptly spray thiophanate-methyl, chlorothalonil and other fungicides.
Colonization
Planting time was planted before and after the frost fall in mid-late October.
Soil preparation and film-covering plots of green onions require 4,000 kilograms of organic manure and 15 to 20 kilograms of compound fertilizer. Plowing 20-25 cm deep, ridging ridges, ridge width depending on the width of the film, usually 2 meters. Spray the herbicide to cover the film.
Cuttings are planted at a spacing of 4 to 620 centimeters. For the convenience of inserting onions on the film, we can weld onions and forks. Welded on 2 meters long steel bars, 11 iron bars roughly 10 meters long, with fingers roughly 10 centimeters apart. Centimeters, the other welding handlebar. When inserting green onion, first use the onion fork in the covered mulching film by 4 to 6 cm of plant spacing pit, and then planting onions into the pit, this kind of farmers homemade cutting onion method is simple and quick, not only save labor and save time. After cutting, be sure to step on the water and water.
Management points
After spring green onions have returned to green, they must promptly remove the flowers they bloom, and let them produce fresh green onions from the Minister as soon as possible. The common people call them baby green onions because these new green onions are the product of this mouthwash. Timely removal of weeds between the rows, and the end of March to early April combined watering 15 kg of ammonium sulfate. At the same time, attention should be paid to the prevention and control of diseases and pests such as leafminers and mantle.
A greenhouse(also called hothouse)is a building or complex in which allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity. Greenhouse may be used to overcome shortcomings in the growing qualities of a piece of land, such as a short growing season or poor light levels, greenhouses are often used for growing flowers, vegetables, fruits, transplants and seedlings. Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass. Commercial glass greenhouse are often high-tech production facilities for vegetables or flowers. The glass greenhouse are filled with equipment such as screening installations, heating, cooling and lighting, and may be automatically controlled by a computer.
