The alpine specialty vegetable "wasabi" and its cultivation points Zhu Jin "wasabi", also known as Behen Vegetable, is a perennial herbaceous semi-shady plant of the Cruciferae family, whose leaves can be fried and rhizomes ground into powder. It produces a special aromatic pungent flavor, has a strong antiseptic and digestive function, and is an indispensable high-level condiment for freshly eaten sashimi and other indispensable condiments. Wasabi like cool and humid climate, the requirements of the growing environment is harsh, only suitable for planting at an altitude of 1000-2000 meters. Now its cultivation points are introduced as follows:

1 Sowing: fall sowing in late September to mid-October is good. When the sand germination of the anemone seeds began to emerge when the embryonic root for the sowing of the right time, before sowing can be used at a concentration of 100 mg / liter of erythromycin liquid seed immersion for 24 hours at a temperature of 13 ~ 16 ℃. Sowing: the average amount of seed per 667 square meters (1 mu) is 1.5 kg, mixed with sand sowing. Spot sowing: open a shallow furrow, rows of plants 10 cm x 4 cm, 3-4 seeds per hole, 1 kg of seed per 667 square meters. Cover the soil thickness of about 5 mm. Wasabi seeds are intolerant of drought, once dry and water loss that is the loss of germination ability, so after sowing the seeds should be watered at the right time. Keep the soil moist.

2 Planting: choose a plot of land with deep, loose and fertile soil, and pre-till the ground 1 month before planting. Wasabi to underground rhizomes as the main product, so it needs deep plowing. Generally about 30 centimeters deep turning, along the slope shape from top to bottom every 1.1 meters to open the border, border width of 80 centimeters. The width of the furrow is 30 centimeters, and the height of the bed is 35 centimeters. The length depends on the terrain.

Sunflower planting in the spring or fall is appropriate, planting period generally spring planting in April around. Fall planting in the end of November is appropriate. The basic principle of planting is "deep plowing and shallow planting". In the planting must pay attention to not planting deep. Mulch should not cover the growing point. If the fibrous roots are too long, they can be cut short and then cut again. Adopt double row planting, plant spacing 50 cm × 40 cm: adopt diagonal planting method, 667 square meters planted about 3,000 plants.
