Cultivation technology management of pea sprouts

Sprouts are grown in a humid environment by relying on nutrients stored in plant seeds, and are all natural organic green foods. Because human life is inseparable from vegetables, and the consumption of vegetables is threatened by harmful substances such as pesticide residues, nitrates, heavy metals and other harmful substances. The sprouts do not need to apply fertilizers and pesticides during the planting process, and also do not use auxin and other substances. After production, they will not spoil after eating and harvesting, which can effectively avoid the loss of vitamins during the storage of vegetables. Sprouts were once called perfect and ideal vegetables by American medical and nutrition experts, and are becoming more and more popular and loved by people. The key cultivation techniques for planting sprouts at home are as follows.

1 Main production tools

Cultivation racks (multi-layer seedling trays can be placed for three-dimensional cultivation), plastic seedling trays, watering cans, wrapping paper, tissue paper, etc. that are easy to absorb water, as well as gauze and perlite.

2 Types and varieties of sprouts

There are dozens of varieties of sprouts: big leaf sprouts, long pea sprouts, radish sprouts, alfalfa sprouts, buckwheat sprouts, black pea sprouts, red bean sprouts, toon sprouts, convolvulus sprouts and peanut sprouts. General pea seedling production uses green pea, brown pea, hemp pea and other food-use pea; Luo b seedlings use white radish, Guoguang radish, Dahongpao Luo b and other autumn and winter Luo b; buckwheat seedlings use Shanxi buckwheat or Inner Mongolia wheat, etc .; Toon can use Wuling Mountain Red Toon and so on. Seeds are required to have good purity and purity, high germination rate, large and full 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 commercial rate and the yield. Therefore, high-quality seeds must be used, and the seeds must be cleaned before sowing to remove worms, broken, deformed, rot mold, deflated grains, Extra small grains and germinated seeds. The seeds of peanut sprouts must be shelled, because peanut seeds will partially lose their germination capacity after two months of shelling. In order to promote the germination of seeds, the seeds after cleaning need to be soaked. Generally, first rinse the seeds with clean water at 20-30 ° C for 2-3 times, and then soak the seeds. It takes 36 hours to soak the seeds of buckwheat, 24 hours for peas and toon, and 6-8 hours for radish. After soaking, rinse the seeds 2-3 times, then remove the seeds, drain off excess water, and wait for sowing.

4 Sowing

Sowing is carried out in plastic seedling trays. Before sowing, the seedling trays are cleaned and disinfected first. Lime water or bleach powder can be used for disinfection, then rinsed with clean water, and then disinfected with Yifuyuan microbial deodorant liquid at a ratio of 1: 100. * Lay a layer of paper on the bottom of the tray to sow the needed sprouts. Note that there is no need to spread paper in the production of peanut bud nursery trays. The amount of sowing is based on the weight of dry seeds, pea is about 500g, dill b75g, buckwheat 150g, toon 50-100g, convolvulus 50-100g, peanut 250g. When sowing, uniform seeding is required to make the sprouts grow neatly and wait for 60% of the seeds Sow again when the buds are exposed. Toon saplings are different from other saplings in sowing and require the following two conditions:

(1) After the paper is spread on the seedling plate, a layer of 1.5cm thick perlite must be spread. The perlite must be added with water in advance, and then squeezed to remove excess water after stirring.

(2) Seeds must be routinely germinated in advance, with a germination temperature of 20-22, and 4-5 days for germination.

5 Stacking

After sowing, stack the seedling trays together and place them on a flat ground to germinate them. Note that the height of the seedling tray stacking and placement should not exceed 100cm, and the interval between each stack should be 2-3cm, so as to avoid excessive depression and poor ventilation to cause uneven seedlings. In addition, in order to maintain proper air humidity, the stack tray should be covered with wet sacks, black agricultural film or double gauze. The germination should be in a place where the humidity conditions are relatively stable, and at the same time should be protected from light. During the germination, the indoor temperature should be maintained at 20-25 degrees, but the toon requirements are stricter and need to be maintained at 20-22 degrees. Water should be sprayed once a day during the germination of stacked discs. The amount of water should not be too large to avoid rotten buds. However, toon does not need to be sprayed, because the moisture retained by the perlite can fully meet the needs. In addition, water should be sprayed at the same time 1 Invert the disk twice, change the position of the seedling plate up and down, make the cultivation environment of each seedling plate as uniform as possible, and promote the neat growth of the seedlings. Under normal conditions, it can be put out in about 4 days. After stacking and germinating, the seedlings are scattered on the cultivation rack for greening. At the time of emergence, the pea sprouts are about lcm high, the radish seed coat is shedding, the buckwheat seedlings are 1-3cm high, and the toon is 0.5-1cm. Both the cotyledons and true leaves are not unfolded.
