Dioscorea zingiberensis is a ginger family that has a health-care effect and is known as "Asian Ginseng." Yanghu ginger has wide adaptability, less pests and diseases, and stable yield. It is cultivated in many towns and towns in Luxi County, Hubei Province. The following small series will talk about the high-yield planting techniques of the sage, for the reference of the majority of growers.
1 Choose a plot to build a shed, finely plan the ground, and apply enough base fertilizer
The stalk of Dioscorea chinensis is erect, with a plant height of 2 to 3 m. The leaves are ovate, apex acute, green, alternate; stems are oblate and irregular, with irregular protrusions; edible parts are tuber, without pericarp, purplish purple, belonging to perennial herb , like fertile, loose, moist, cool soil environment, more resistant to yin, not resistant to high temperatures and glare, withered leaves and leaves withered.
It should be planted in a neutral soil plot with leeward, deep and loose soil layer, convenient water source and pH 6~7. The construction of the greenhouse is the same as that of the general facilities. The construction of the shed should be completed in mid-September. At the end of September, the land preparation will require the soil to be broken, flat, even and solid. After the ground is well-formed, it is used as a compartment with a width of 1.2m. The width of the trench is 50cm, the width of the cabin is 70cm, the depth of the trench is about 40cm, and the length is limited to the plot.
667m2 of mature farmyard manure 5000kg or human excrement 10 (1 burden = 50kg, the same below), can also use biogas slurry; if using fertilizer, 667m2 can be used ternary compound fertilizer 200kg, plus 2kg of zinc sulfate. Fertilization method: first take a small ditch 40cm deep in the middle of the carton, then mix the fertilizer into the ditch, then backfill and close, and take a small ditch on both sides of the fertilization ditch, 20cm deep to be planted.
2 Choose the ginger, and broadcast it in time.
2.1 Selection and disinfection
Choosing a kind of ginger is the key to achieving a full seedling, and the ginger can be purchased locally. After the ginger is transferred back, the sun is dried first, and the ginger and the rotted ginger are removed. Qualified ginger is sterilized with 50% carbendazim WP 300 times solution and 10% dikesone (disulfonate sodium) emulsifiable concentrate 300 times. It can be dried in good weather for 2 days, which can be used for disinfection.
2.2 Planting density
The amount of seeding varies depending on the size of the ginger, which is generally 800 kg/667 m2. Because the yam ginger is mainly used for tillering, the sown must have 2~3 whole buds, and the good germination of the buds can be thinned. The spacing between the plants is 30 cm×60 cm. Point, the plant spacing is 20 cm × 60 cm, and the density is about 667 m2 / 4000 plants.
2.3 Sowing time
Timely early broadcast is the key to ensuring the morning market. In the autumn of the greenhouse, the low mountainous area of ​​Luxi County can be planted in early October, the second high mountain area can be planted in the middle and late September; the spring sowing, the low mountain area is planted in mid-February, and the second high mountain area can be planted in early March, which is beneficial for early germination. The foundation is laid under high yield.
2.4 insulation and moisturizing
After the ginger is planted, the root water should be poured, and then the mulch film should be covered to achieve the purpose of warming and moisturizing, thereby promoting the early development of new roots.
3 Post-plant management
1 timely rupture of the membrane when the ginger seedlings should be ruptured in time to prevent burns.
2 If the water management encounters drought, it should be filled with water in the ditch.
3 timely shade after the end of March with shade nets in time to shade.
4 timely ventilation when the temperature inside the shed exceeds 25 ° C, ventilation and cooling.
5 timely topdressing in spring after emergence, combined with cultivating and weeding, each 667m2 will dilute 2~3 manure excrement twice to pour the seedlings. In the second year before the winter, combined with 667m2, apply 3000kg of decomposing farmyard manure or 10 manure excrement or 50kg of compound fertilizer to ensure the safe wintering of ginger to lay the foundation for the next year's high yield.
6 Commodity ginger harvest Yanghu ginger should be harvested before the buds are unearthed after they are unearthed. Although the quality of the harvest is too early, the yield is low, and the fiber is coarse and the quality is deteriorated. Therefore, the autumn-sown shed commodity ginger was mined and listed in early March, and the spring sowing can be mined and listed in mid-July. The open-field live ginger was mined in August.
In the Luxi County of Hubei Province, the planting of Hujiang ginger is generally about 6,000 m2. The yield of 667 m2 is about 1000 kg. The greenhouse is planted with greenhouse ginger, with an average yield of 2,580 kg of 667 m2. It is listed in the middle and late March, 4 months ahead of the end of July. Left and right, according to the current market price of 60 yuan / kg sales, 667m2 income of more than 70,000 yuan. The market potential of Yanghu ginger is huge and it is a good project for farmers to get rich.
