Sprouts are grown in a humid environment by relying on the nutrients stored in plant seeds, and are all natural organic green foods. Because human life is inseparable from vegetables, and eating vegetables is threatened by excessive levels of harmful substances such as pesticide residues, nitrates, and heavy metals. "Ning was poisoned and can not starve to death" is the helplessness of most people on the status quo of vegetable production. Sprouts do not need to apply fertilizers and pesticides during the planting process, and do not use auxin and other substances. After production, they will not be spoiled, which can effectively avoid the loss of vitamins during storage. Sprouts, once known as perfect and ideal vegetables by American medical and nutrition experts, are becoming more and more popular and popular. The key cultivation techniques for home planting sprouts are now described below.
1 main production tools
Cultivation racks (multi-layer seedling trays can be placed for three-dimensional cultivation), plastic seedling trays, watering cans, water-absorbing packaging paper, tissue paper, etc., as well as gauze and perlite.
2 Sprout species and varieties
The main types of sprouts include dozens of varieties such as big leaf pea sprouts, radish pea sprouts, radish seedlings, seedlings, buckwheat seedlings, black bean seedlings, red bean sprouts, camphor buds, spinach seedlings and peanut buds. In general, pea seedlings are produced with green peas, brown peas, peas and other peas; the broccoli seedlings are white radish, Guoguang radish, Dahongpao, and other autumn and winter radish b; buckwheat seedlings are used in Shanxi buckwheat or Inner Mongolia to raise wheat; The fragrant scent can be used in the Wuling Mountain red fragrant pot. Seeds require good purity, good clarity, high germination rate, large, full-bodied seeds, and no pollution.
3 seed treatment
The quality of the seeds is closely related to the uniformity of the growth of the sprouts, the commodity rate and the yield. Therefore, it is necessary to use high-quality seeds, and before the sowing, the seeds should be cleaned, and the insects, broken, deformed, Pythium, and glutinous grains should be removed. Extra small granules and seeds that have been budded. Seeds that produce peanut sprouts must be shelled because peanut seeds partially lose their ability to germinate after two months of shelling. In order to promote seed germination, the selected seeds also need to be soaked. Generally, the seeds are washed 2-3 times with 20-30 ° C clean water, then the seeds are soaked, the buckwheat soaking takes 36 hours, the peas and citron are 24 hours, and the radishes are 6-8 hours. After soaking the seeds, wash the seeds for 2-3 times, then remove the seeds, drain excess water, and wait for sowing.
4 sowing
Sowing is carried out in a plastic seedling tray. Before seeding, the seedling tray is cleaned first, disinfected first, disinfected with lime water or bleaching powder, then rinsed with water, and then disinfected with Yifuyuan microbial deodorant at a ratio of 1:100. Finally, a layer of paper is placed on the bottom of the plate to sow the desired sprouts. Note that there is no need to lay paper in the peanut bud seedling tray. The seeding rate is about 500g of peas, about 500g of peas, 150g of buckwheat, 150g of buckwheat, 50-100g of spinach, 50-100g of spinach, and 250g of peanuts. It is required to sow seeds evenly when sowing, so that the sprouts grow neatly, wait 60% of the seeds. Sowing when the shoots are budded. Different from the other seedlings, the camphor sprouts require the following two conditions:
(1) After the seedling plate is laid, a layer of 1.5cm thick perlite should be laid. The perlite should be added with water in advance, and the excess water should be squeezed out after stirring.
(2) The seed must be routinely germinated in advance, the germination temperature is 20-22, and the germination time is 4-5 days.
5 stacked germination
After the sowing, the seedlings are stacked together and placed on a flat ground for stacking and germination. Note that the seedling stacking and placement height should not exceed 100cm, and each sputum should be separated by 2-3cm, so as to avoid excessive stagnation and poor ventilation. In addition, in order to maintain proper air humidity, the top of the tray should be covered with wet sacks, black agricultural film or double gauze. The germination should be in a place where the humidity condition is relatively stable, and at the same time, it should be protected from light. During the germination, the indoor temperature should be kept at 20-25 degrees, but the requirements for the citron are stricter and need to be kept at 20-22 degrees. During the germination of the stacked discs, the water should be sprayed once a day, so that the amount of water should not be too large, so as to avoid rotten buds, but the scent does not need to be sprayed, because the moisture retained by the perlite can fully meet the needs, and should be carried out while spraying water. The second reversal, change the position of the seedling tray up and down, so that the cultivation environment of each seedling tray is as uniform as possible, and promote the tidy seedlings to grow neatly. Under normal conditions, the tray can be released in about 4 days, the stacking germination is finished, and the seedling tray is scattered on the cultivation rack for greening. When the plate is released, the pea sprouts are about 1 cm high, the radish seed coat is shed, the buckwheat seedlings are 1-3 cm high, the citron is 0.5-lcm, and the cotyledons and true leaves are not unfolded.
