Sprout vegetable cultivation is a kind of vegetable factory and intensive production method that has emerged in recent years. It can produce sprouts all year round. The seed buds of citrons are softer and more concentrated than citron shoots. They can be rooted and eaten. The market is very good. The method for cultivating live citron buds by this method is described below.

First, production of live buds

1, the suitable temperature range is 15 °C ~ 25 °C, generally winter and spring in the indoor or greenhouse production.

2. Stereo planting in an effective space. Use wooden boards or bricks to form a shelf. Seedling trays are made of lightweight plastic trays with mesh at the bottom. It is appropriate to have a length of 50 cm, a width of 25 cm and a height of 5 cm. A hole is required at the bottom of the tray to facilitate water leakage.

3, seed treatment. The saponin seeds collected in that year were removed by removing the impurities (the germination rate of the seeds was very low every other year), immersed in warm water of 55°C, and continuously stirred. After the water was cooled, the seeds were soaked for 10 to 15 hours, and then the germination was taken out; the germination temperature was 20 °C ~ 25 °C, germination process at least two times a day, can make the seeds germinate. About 4 days, the seeds are white and sown.

4. Spread a layer of white paper on the bottom of the washed plate. Spread a layer of wet sand with a thickness of 2 to 2.5 cm on the paper, and then evenly soak the seeds on the substrate. The sowing rate per square meter is 500. Grams, a layer of 1.5 cm thick fine sand was placed on the seeds, and the seedlings were poured with 20°C water.

Second, management

Five days after the seeds were sown, the seeds exposed the substrate and the substrate was then thoroughly drenched with fresh water at 20°C. Usually should pay attention to regular water spray (hand held watering can or sprayer), spray 2 or 3 times a day, do not submerge the water, the temperature is maintained at around 25 °C during the day, about 10 °C at night, pay attention to moisturizing, so 5 to 6 days later The scented pods of the citron have begun to bulge. When the cilantro shoots grow to about 10 cm, the cotyledons can be consumed when they are fully flattened. Axillary buds tend to grow true leaves because the temperature is too high, and the value of the commodity is reduced. A roughening agent can be sprayed on the bud top at a distance of 1 to 1.2 cm from the sand layer.

Third, harvest

Live buds need to be shaded at the early stage of production. When the bud grows to 8-9 cm, but not lignified, see the light again, and then dry it for 1 or 2 days, so that it can be harvested and harvested. It can be harvested from 3 to 4 per square meter. Kilograms of fresh alfalfa sprouts.
