How to grow onions? How to grow onions
The onions prefer cooling, mostly spring and autumn, so that they can be planted at temperatures above 7°c. With well-drained, permeable, soil-defunct and fertile soil, soil before planting is used, sufficient fertilizer is applied to ensure nutrients, and sufficient moisture is humid. When seeds have been selected, they are planted on the soil, covering about 1 cm of thin soil, with light pressure, plastic film, and good light。
Timing and management of organic cedars
Before choosing to plant cedars, consider which varieties to grow, as different varieties have different harvest times, as well as different areas suitable for cultivation, and the selection of suitable varieties is important. 2. The method of breeding the seedlings is selected in the form of a den-creasing nursery, which is followed by the preservation of the seedlings with a sun-covered net, the use of all-day shades in the morning before the seeding, and the application of fresh water once a day, once a noon examination, the discovery of water shortages and the timely replanting. 3. Fertilizers are applied in the whole area. Deep-planted dredges are then made into deep trenches with a width of 0. 8 m and a width of 0. 4 m, with a range of 50 cm and a range of 3-5 centimetres per acre of corroded organic fertilizers, compound fertilizers (15:15:15:15:15) 50 kg, urea 10 kg and boron 0. 5 kg. 4. Field management may increase the frequency of water recharge when the temperature is too high, but be careful to prevent the death of the seed. When it is slow, it is properly controlled and then required to produce sufficient water to facilitate rapid growth of the nutrients. Adequate water supply should be maintained during periods of booming growth and expansion. It is also important to catch fat, especially when the ball is present and can be followed by a three dollar compound fertilizer of 20 kg+ urea 15 kg per acre. 5. Pest control. There are more pests, mainly beetling night moths, moths and green beetlings, and early detection of early treatment is required, with the selection of high-efficiency low-toxic insecticides, such as 10 per cent amphibian + 10 per cent amphibian (darts) 500 times the fluid, 30 per cent acetate carbide (stable enemy) 1,000 times the fluid, 14 per cent avimite 800 times the fluid, 1. 14 per cent acetal salt 500 times the fluid, combined with physical control, such as frequency-fibration lamps, sexual seductions and sugar vinegar, to ensure safe consumption of vegetable products。
What is organic cultivation
Organic cultivation is the method of cultivation using natural raw materials, using safe and rational methods to fertilize soil, combat pests and diseases (including soil improvement, fertilization and pest control, with strict standard controls over the fertilizers used) to obtain safe and harmless crops。
Traditionally grown and wildly grown plants are fully free to grow, following plant production patterns, and rely on their own means to cope with changes in the external environment (e. G., the planting of human and animal waste)。
Organic farming yields are relatively lower than traditional cultivation, as both fertilizers and pesticides allow for better control of the traditional plants, although the disadvantage is pesticide residues, while organic pest management is relatively difficult。
However, the production of organic crops has varied considerably, with some of them producing much less than traditional cultivation methods, while others are already close to traditional agriculture. How can we grow our own organic vegetables at home
How to grow organic vegetables at home is now starting to move on to the consumption table for some people. But it's hard to get real organic vegetables on the market. As a result, a large number of cabbage partners have chosen to grow organic vegetables at home, which are an environmentally friendly and healthy way of life and, more importantly, can be eaten with comfort. Now teach us how to grow organic vegetables at home. It's really important that you grow vegetables on the roof of an apartment, on the balcony, or on the courtyard. Summer crops: melons, guavas, eggplants, beans, cabbage, cabbage, tomatoes, winter crops: spinachs, mustards, kale, cabbage, carrots... And crops suitable for the four seasons, such as cyanide, guacamole, four-quarter beans, onions, etc. The seeds are now packaged in the back of their growing season, and the seed shopkeeper is your best vegetable advisor. You can go to the flower market, the horticulture shop, the seed shop, the organic shop. Seeds can be bought together, either medium soil or cultured soil, or ordinary farming land, mixed into organic compost or medium soil, in a large proportion of 1:2 to 1:4; qualified composting can be bought in the flower market and in the marketing department. In fact, you can go back to the mountains or to the creeks and dig up your soil, which is rich in microbes that make your soil organic. The soil is later the home of vegetables, on which the day after tomorrow is dependent. So, healthy soil, healthy vegetables. But what's good soil? Look at the soil section of our hiking area. The ph value for soil can be tested in a simple way and the suitable ph value for ordinary crops is approximately 5. 5 ~ 6. 8. Ph-value test: the soil and water are combined in containers at a ratio of 1:2 and are tested on ph-team paper in about 30 minutes, and the ph-paper general-chemical material is sold at the ph-team. Before filling up the soil and putting it in your container, you have to process it. If you don't use the pots that you bought, you use the house like the dabori box, the bucket, the wooden box, you have to drill a few holes underneath, and then you put a veil on the hole, and you don't fall out. Keep it loose when you fill it, and don't press it so the soil has air. It's best to have a water dish under the container. Six seed sprouts put the seed you bought in the water for the sprouts, and the water can be contained in a container like a sap. Water can soften seed skins and activate embryo root. Temperature is also an important factor, but each vegetable seed has a different personality, and it is best to ask the owner of the seed shop, usually in a cooler place, such as the fridge's fruit and vegetable freezer. In the back of the seed packaging, there will be a warm bud of cooking, which is a good reference. The breeding species can be divided into three types of vegetables: direct sowing, seedling and branching. Direct seed planting: if you put the seed in the ground, and then you put it on a normal field, then you add organic compost or medium soil, and then you cover about a centimetre of the soil, and as for the spacing of the seed, the principle is that the larger the crop, the greater the distance, you can imagine the situation in the field, and you can sort it out in one line, which is the size of an empty cabbage, the size of an empty cabbage, the size of an empty cabbage, the size of a green river, the size of a white cabbage, the size of an empty cabbage. Cultivation: the seeding of seedlings to the lair, the generation of seedlings to the soil, like cucumbers, and eggplants, tomatoes, and kale are best seeded. Caves are bought in places such as the flower market, where they are first filled with earth in a hole (the best medium of soil), then they are sprouted and then covered. It's also called "poaching" which, like taiwan's markets, has lots of melon leaves and veggies, which are the right way to do it. Eight seedlings are finished, so you can water the whole soil until it's wet, then you can put on a wet newspaper, you can keep it wet and you can keep it? When you see a seedling coming out of the ground, you can remove the paper. Nine saplings, seeing a sap, is a big step forward. Seeing the seedlings, if it's too dense, you can adjust their space so that every dish has its own space, and you can pull up bad seedlings, or you can cover them in the ground. In principle, water is watered once a day, once a day, even once a day in the rain, preferably at a fixed time, and crops grow better. Fertilizer management, which takes about 7 to 10 days to fertilize, buy organic composting on the market, or ask the owner of a tofu shop or soy sauce shop for some bean curds, bury them in the ground, don't hurt the roots, the closer the better. 12 pest management, one kind of dish, you'll be surprised that these bugs really know what they're gonna do. You can make your own natural pesticides, pepper and garlic, spray them on the leaves. The harvest is in the middle of a series of rainfalls, because if the vegetables are not luminous enough, they will mutilate the nitric acids, and no fertilizer, no harvest days before the harvest, the roots can be kept, and some of the vegetables will grow new seedlings, otherwise, if you mix the soil, a few times later, your soil will become very fertile. The method of planting organic vegetables at home has been introduced, and the use of the household balcony and courtyards has many functions, so that the family can grow some organic vegetables, so that it can entertain itself and enjoy the pleasure of growing them with the family!
