First, greenhouse cultivation
1. The best choice for seedbed finishing is to use sandy loam soil for leeward sun, near water sources and transplanting sites. Seedlings are first watered to promote hoeing, then deep plowing and smashing, smashing finely. Then open the rake, stove ash, plant ash, sand, soil, fertilizer, and then spread a fine layer of soil. According to the way of raising seedlings, it is generally better to manage them.
2. Seedlings treatment The sugarcane stems normally used for breeding are not cut off during nursery, and then cut off when transplanted into the field. If the damage to the sugarcane is large, it can be cut into two buds or three buds. Then use 2% lime water soaking seeds for 10-14 hours or soaking with 50% ammonium zinc 400 times for storage and germination.
3, cane seedlings emission is different from seeding. The entire nursery should be aligned and the buds should be laid sideways. The sugarcane species is separated by one finger. When you put the seed, use wet soil to fix both ends to avoid rolling.
After the cane is discharged, the cane is poured with 1% lime water and then covered with 2 cm, not too thick.
4, temperature control water shed temperature should be maintained between 20--30 °C, more than 35 °C to water or film cooling, lower than this 15 °C should pay attention to warm, cover straw at night. The sprouting of sugarcane is sensitive to moisture. If the water content in the stem is lower than 50%, the germination rate will be significantly reduced. It is especially important to keep the soil moist.
5, timely broken stems when transplanting when the seedlings can be 3-3-5 leaf age seedlings can be broken stems, such as the requirements of higher yield, fertile seedlings to 6--7 leaf cane seedlings till the time after transplanting field.
Second, the plastic greenhouse arch nursery due to the greenhouse temperature, humidity and soil temperature is high, can increase the rate of emergence of sprouts and emergence rate. The width is determined according to the width of the shed film, generally 0.3-0.5 meters narrower than the shed film. (Other steps are the same as above)
1, cover film under the completion of the cover film. Before the film is covered, the long bamboo pieces are used to bend the arch brackets into the seedbed; then, the cover film is used, and the edges of the film are pressed with wet soil; the grass curtain is covered to help increase the soil temperature and promote germination.
2, seedbed management cover film, the temperature within the shed, to check at any time, more than 35 °C to remove film or water cooling, to prevent burns cane seedlings. The temperature inside the inspection booth should be at noon on sunny days. The coated nursery bed is prone to drought in the border and the soil moisture is inconsistent. Therefore, timely watering should be done to keep the seedbed moist. If yellow weak seedlings appear, urea water should be used to raise seedlings in time.
3. Seedlings growing from the seedlings grow to 2 or 3 pieces at a time, and they must be uncovered at noon or during the day so that the seedlings can gradually adapt to the external environmental conditions.
Third, the large arch shed nutrition seedlings Nursing seedlings nursery good quality, no fear of drought when transplanting, return green, high survival rate, high yield, but also save land and sugarcane species. (Other steps are the same as above)
1. Prepare nutrients for vegetable garden soil, farmyard manure and fine river sand to form nutrient soil, and then use soil-filled plastic bags with a diameter of 8-10 cm and a height of 14 cm to make soil mulches. /4).
2, cane species cut single bud stem section.
3, put a good base fertilizer, put the seedlings placed in the pot, and then add the pot into the digging a good nursery pit, and then watering, cover 1- 2 cm fine soil, and finally cover the film. 45 days after seedling age removal and transplanting
North Sugar Cane Seedling Technology
The northern species of sugarcane is different from the south, and artificial breeding must be adopted in production. This is the key to the success of northern species growing. Seedlings can not only save sugarcane seedlings, ensure that seedlings are fully grown, but also advance and prolong the growth period of sugarcane, which is conducive to early maturing and high yield and high sugar content. In Hebei and Beijing-Tianjin regions, the nursery was generally started around February of the lunar calendar, and transplanted to Daejeon 45 days after the seedling stage. According to their own conditions and species of cane area, timely adoption of greenhouse cultivation seedlings, plastic greenhouse seedlings or nursery nutrition seedlings. The method of operation is as follows.
