Spores cultivation techniques

Spores and orchids are a variant of Brassicaceae. The early stage of the plant is like Gan Lan. After the bolting, there are many leaflets growing between the leaves. These leaflets are edible parts. The sporocarp is a western food. Its edible method is the same as Ganlan, but it can also be frozen and processed. First, the requirements of environmental conditions 1, temperature and light spores Ganlan adapt to the cold climate, frost-resistant, able to withstand the temperature of minus 10 °C, the suitable temperature for plant growth is 18-22 °C; not high temperature, 23 °C can not develop Leaflet ball. The production of spores and orchids in autumn and winter with large temperature difference between day and night produces high quality and good quality spores. High temperature and humidity can cause cracking and decay of the leaflets. The whole growth period requires sufficient sunlight, the light is insufficient, the plants are easy to grow, the leaves are small, and the yield is low. The length of the sunshine only affects the flowering. 2. The moisture requirement of water spores is similar to that of broccoli. 3, soil nutrient spores Ganlan suitable for growth in soil pH6-6.8. The required nutrition is similar to that of broccoli. Second, the cultivation techniques 1, select varieties and sowing dates better varieties of ball-bearing Japan's early child holder, son holding, the United States Jada Cross F1, etc., autumn, winter and spring can be planted in three quarters, preferably in autumn and winter. 2. Seeding Broccoli Seedling and cultivating techniques can refer to broccoli. The seedling age of spores is 35-45 days. 3, planting specific practices also refer to broccoli, planting distance is 50-75 cm, spacing is about 75 cm. Dwarf varieties are properly sparse. The species of Gaosheng is densely planted. 4. Field management moisture management is similar to broccoli. The top dressing is generally divided into four times: the first time after the planting and survival, the thin fertilizer is chased for the plant to restore growth; the second time after one month, the top dressing is applied to promote the vegetative growth of the plant, and the leaves reach about 40 pieces; the third time the top dressing is applied to the lower leaflet. When the ball starts to expand, it promotes the development and expansion of the leaflets. The fourth topdressing is carried out when the lower leaflet begins to harvest and promotes the expansion of the upper leaflet. When the plant grows to 40 cm tall, use bamboo or tree branches as a support to prevent lodging. According to the field conditions, cultivating, weeding, and cultivating the soil. The poorly-developed leaflets should be removed in time, and the old leaf that obstructs the expansion of the leaflets should be cut off. 5. Pest control is the same as broccoli. Third, the lower part of the harvest of the first mature ball, generally 2.5-5 cm in diameter when the leaf ball harvest, with a knife along the stem to cut the ball. Too late to harvest leaves the ball cracking, rough texture, affecting the value of goods. General production of 700-1000 kg per mu. The spores and orchids were pre-cooled in time after harvest, and they were preserved for 40-55 days at a temperature of 0°C and a relative humidity of 95-98%.
