Preparatory work: sterilisation of seedlings with 0. 4 per cent of formaldehyde solution, followed by clean drying, followed by the selection of pure seed varieties, high gestation rates and full granules。
2. Treatment of seeds: dismantling of bad seeds and immersing with hot water for a period of time, during which the water is mixed up and water temperatures decline and soak for several hours with fresh water, before cleaning up the leachate and filling it in the container。
3. Cultivation: the newspapers are spread evenly, covering the empty basins, by laying them on the nursery and wetting them。
4. Sapling management: watering, sunburning, etc。
I. Earthless planting techniques for radish seedlings
1. Preparatory work
Packagings prepared for planting are usually prepared for special nursery trays, where 0. 4% of formaldehyde solution is used for disinfection. If the amount is very large, some water can be immersed for a period of time directly by bleaching. Clean it up and dry it up. It's better to choose the precipitator and manage it better. Select seeds that are easy to germinate, well-breeded, pure varieties, full and large grains。
2. Treatment of seeds
Seed water selection, removal of drifting seeds, missing seeds, and then 50 degrees of hot water to immersion, which will gradually decrease in water temperature for 10 minutes, can stop mixing at more than 20 degrees. The water is immersed for a few hours, and the water is enough to clean it. The leaching is followed by the entropy in a container. The induction temperature is 25 degrees and the temperature is maintained, and the bottom of the container must be permeable。
3. Sowing cultivation
Get a clean nursery plate, a paper and a water-squeezing paper, so that all the paper is wet. Some of the seeds that have become white since the seeding have been spread evenly on the seedlings, sowing a piece of paper that can penetrate the seed, then using an empty basin to ensure that the light is not seen, and then discharge in sequence on the shelf。
4. Shrimp management
Weak light is received before sprouts, water is poured once a day, seedlings are grown to 4 cm high, nutrients are used with water, water is poured three times a day, and a little nutrient is added at one time. When the leaves are about to spread, there is a need for enough sunlight and increased light, but strong light is unacceptable and can cause loss of water. The light rises and the corresponding water is increased four times a day. The leaves spread very quickly, so they can harvest。
Ii. How to avoid suffering by planting sprouts
1. Sapling processing and disinfection
(1) there is a need to acquire flat-floor plastic saplings from the market for sprouts, which, if not available locally, can be made from aluminium alloys and plastic veils. Aluminium alloy bars with a width of 5 cm are first used to process a rectangular frame of 50 cm, 27 cm wide and 5 cm high, which can be used as a sap with small screws and thin aluminium bars on its floor。
(2) prior to each production, a 500-fold potassium permanganate water solution (1 gram of potassium permanganate vs. 500 g of water) will be required to wash the sapling, disinfect the bacteria and prevent the occurrence of the disease, after which clean water will be used to wash the sprouts。
Seed treatment
(i) seeds for the production of sprouts, often with radish seeds, pea seeds, soybeans, green beans, soybeans, black beans, etc. These seeds need to be impregnated before they germinate in order to promote rapid growth and disinfect them so that the disease does not occur。
(2) seeds such as soybeans, green beans, green beans, green beans, black beans, peas, peas, etc. Must be selected for the new seed of the year, carefully screened, broken seed removed, then drifted with water, removed the tarp, purified water, then immersed the seed in a solution of 500 times the potassium permanganate for 10-20 minutes, then washed the liquid, immersed it in the water for 18-20 hours, so that the seed can suck up its moisture。
(3) there are a small number of hard grain seeds in the pulse seed, which are difficult to absorb, which, when immersed, sink to the bottom of the water. For this small part of the seed, a rapid mixing in hot water of 60-80°c is required, and when the water temperature is reduced to 30°c, it continues to immerse for 12-20 hours until the seed is soaked and soaked。
(4) carrot seeds, which, after screening, are washed with water at 20°c to remove drifting granule seeds, and then impregnated with 500 times the potassium permanganate water solution for 20 minutes. They are then immersed in water at 20-25°c for four hours and seeded in clean water。
(5) in order to increase the nutritional value of sprouts, seeds can be immersed with calcium glucose acid + 5,000 times vitamin c + 3,000 times organic silica, immersed seeds, increased levels of calcium, magnesium, potassium and vitamin c, 500 times more than potassium nitrate and magnesium sulphate + 500 times more。
Seeding
(1) the application of flat-floor nutrient plates, which, because of the size of the hole in the base of the plate, leaks seeds, requires the laying of a sheet of toilet paper at the bottom of the plate, or of white and clean gauze with boiling water, or of unwieldy sheeting with perforated water, stretching to the right level, overwhelming the bottom and preventing leakage。
(2) the planting needs to be spread evenly, in an appropriate amount, with only one seed being sowed, so that the seed is covered in a whole base, without displaying the cloth or toilet paper laid on the floor, and without overlap, it is appropriate。
Sapling management
(1) saplings of every three to five seedlings will be placed in an integrated top-down and suitable temperature. The top sap, covered with hot-watered white cloth. Peas seedlings and radish seedlings with a suitable temperature of 15-20°c. Other saplings of pulses, with germination suitable for temperatures of 25-30°c。
(2) saplings that have been sowed with seeds are required to be filled with clean water with a canteen or sprayer, each sprayed with seed from the sap, with peas and carrots at 20°c and other saplings at 28°c。
(3) during the shower, a basin of about 65 cm in diameter is prepared in advance, with two straight rods placed parallel to the basin, which are removed from the sap on the top, placed on the bar above the basin and washed with water。
(4) be careful not to over-regulate the water, so that the seeds in the seedlings can be rinsed to the drops. Washed dishes, re-positioned, and then picked up another so that they could be washed one by one and rotated。
(5) after the seed has sprouts, after four to six days, seedlings can grow up to about five centimetres above the base of the upper plate, at which point they need to be released individually to light and green. The next day you can eat。
Note by the secretariat
(1) the sprouts cannot exceed seven to eight days in order to avoid aging, increase fibres, reduce quality and lose edible value。
(2) if the sprouts are under conditions of strong light and water scarcity and the length of the embryos exceeds 10 mm, the taste is bound to be bitter. It is usually possible to ensure a very good taste, as long as the sprouts are produced。
