The morphology of corn shoots is similar to that of normal corn in our country, but the appearance quality and internal quality are different from those of ordinary corn. The ear length of corn sticks (shaped like small bamboo shoots) is the purpose of harvesting. It is one of the most novel canned vegetables in the world that can be harvested from the harvested corn cobs. In recent years, more than a dozen villages in three townships in Nanjing County have developed 1000–1333hm2 of bamboo shoots each year. During the shooting period, many merchants from the quick-frozen plants and canneries in southern Fujian’s Golden Triangle region and Guangdong’s Shenzhen and Shantou have come to buy. Fresh corn shoots. With the improvement of people’s living standards and the demand for diversified foods, the development of such characteristics as corn shoots is promising. FEATURES CHARACTERISTICS Maize shoots are fibrous roots with well-developed roots and strong branches. Stems are intermediate, 16-18. Plant height 210 ~ 220cm, stem diameter 1.5 ~ 2.3cm. The leaves are alternately arranged, the total number of leaves is 16 to 18 leaves, short ligule, the leaves are wavy and have hair on the surface. Male flowers are panicles, planted at the top of the plant and yellow pollen. Male and female plants with different sexes are panicle inflorescences, with 10 to 13 nodes for the bearing and 4 to 8 bamboo shoots (2 to 4 main shoots and 2 to 4 side shoots). In the case of timely picking, the bamboo shoots were 5.5 to 12 cm long and the transverse stems were 1 to 1.8 cm long. The unpollinated fresh bamboo shoots were pale yellow and shiny, and the grains were arranged neatly, the tissues were tender and crisp, and the aroma was rich. It is a temperature-sensitive type, and the total accumulated temperature from sowing to harvesting shoots is 900-950°C. It can be planted in three seasons in the southern plains and two seasons in the mountains. From sowing to harvesting: spring sowing 78 to 69 days, summer sowing about 65 days, autumn sowing 54 to 61 days, mining shoots about 15 days. General 667m2 oyster spike 750 ~ 850kg, produce fresh bamboo shoots 180 ~ 200kg. Wide adaptability, strong resistance. The soil requirements are not strict, and paddy fields and mountains can be planted. Cultivation techniques 1 Proper sowing When the temperature is stable through 12 o'clock, it can be sown. Seed sowing in Fujian Province from early March to mid-September. According to market demand, a flexible grasp of the sowing period. 2 Double planting planting planting width 1.2m (including ditch), double row planting, 667m2 sowing around 3500 points, sowing 3 seeds to stay 2 to ensure the number of 667m2 knot bamboo shoots for more than 7000. 3 heavy fertilizer application of corn shoots growth period is short, generally 667m2 need about 9kg of pure nitrogen, nitrogen, phosphorus, potassium ratio of 1:0.7:0.8 is appropriate. Phosphate should be 80% base fertilizer. NPK fertilizer should be re-applied at the early stage of the festival. Fertilizer should account for about 70% of the total amount. Fertilizer should be combined with earth to prevent lodging. 4 Fine management of the 3-leaf period, supplementing the seedlings, and applying a strong seedling fertilizer after 2 to 3 days. In the middle and late period, the seedlings used balance fertilizer. Pay attention to drainage in spring sowing, in case of drought in autumn, it is necessary to timely infuse horse water. The shoots and leaves of corn shoots have high sugar content and are vulnerable to aphids and should be controlled in time. In order to ensure the quality of fresh bamboo shoots, it is not appropriate to use chemical pesticides 15 days before harvest. 5 In time, the male and female flowers were taken out from the top of the plant, and they were completely emasculated with freehand methods. Otherwise it will affect the inherent quality and yield of fresh bamboo shoots. 6 Timely harvesting Harvesting timely and mastering harvesting techniques are the key to ensuring the quality of fresh bamboo shoots and increasing production. When harvesting, leave 2 to 3 sections of the female stems, and two side shoots will be issued on both sides of the panicle after harvest. The first shoot harvesting time can be harvested on the second day after the first temporal spikes reveal the temporal leaves. The 2nd to 4th bamboo shoots and side shoots should be harvested on the day that the filaments show the temporal lobe. However, it must be based on the thickness and length of bamboo shoots. Ensure that shoots with transverse stems are ≤1.8cm in length and 5.5 to 12cm in length to meet export standards.
