Seedling raising is beneficial to early maturity and High yield of Sugarcane artificial Seedling techniques of Northern Sugarcane

The planting of sugarcane in the north is different from that in the south, so it is necessary to adopt artificial seedling breeding technology. Raising seedlings can not only save sugarcane seeds, ensure the whole seedling strong, but also advance and prolong the growing period of sugarcane, which is conducive to early maturing and color conversion, high yield and high sugar. In Hebei and Beijing-Tianjin areas, seedlings are generally raised around the second month of the lunar calendar, and after 45 days of seedling stage, they are transplanted to the field. According to their own conditions and the area of planting sugarcane, timely adopt greenhouse greenhouse, plastic greenhouse, large arch greenhouse nutrition bowl to raise seedlings. The method of operation is as follows:

Sugarcane seedling

1. Raising seedlings in greenhouse:

1. Seedbed arrangement: it is best to choose the sandy loam soil near the water source and transplanting site as the sugarcane seedbed. The seedbed is first watered to promote moisture, and then deeply ploughed and raked, broken and fine. Then open the bed, apply furnace ash, plant ash, sand, soil and fertilizer, and then spread a layer of fine soil. The width of the border is determined according to the way of raising seedlings, and it is better to facilitate the management.

2. Seed stem treatment: the stem of sugarcane commonly used for breeding is not cut off when raising seedlings, but then cut off when transplanting in the field. If the sugarcane bud is damaged, it can be cut into two or three buds. Then soak 10 Murray in 2% quicklime for 14 hours or soak in 400 times of 50% ammonium zinc, then store the buds and germinate, and then release the seeds.

3. The discharge of sugarcane species: seedling metering is different from direct seeding. The seedlings of the whole plant should be arranged neatly and the buds should be placed horizontally. The sugarcane species are separated by one finger. When planting, fix both ends with wet soil to avoid rolling. After discharging the sugarcane seeds, sprinkle the sugarcane seeds with 1% lime water, and then cover the soil with 2cm, not too thick.

4, temperature control and water control: the temperature of the shed should be kept at 20 ℃ 30 ℃, more than 35 ℃, drenched with water or film removed to cool down; if it is below 15 ℃, pay attention to keep warm and cover the straw curtain at night. The germination of sugarcane seeds is sensitive to water, for example, if the water content in the sugarcane stem is less than 50%, the germination rate will be significantly reduced. It is particularly important to keep the soil moist at all times.

5. Timely stem breaking and transplanting: when the sugarcane seedling is 5 leaf age, the stem can be cut off. If more high yield is required, the seedling can be raised to 6 Murray 7 leaves. After the sugarcane seedling is tillered, it can be transplanted to the field at the right time.

Second, raising seedlings in the plastic arch shed: due to the high air temperature, humidity and soil temperature in the shed, the early emergence rate and emergence rate of sugarcane buds can be increased. The width of the border is determined according to the width of the greenhouse film, which is generally narrower than that of the greenhouse film by 0.3 cents and 0.5 meters.

2. The sugarcane species were cut into single bud stem segments.

3. Planting: after installing the base fertilizer, put the sugarcane seedlings in the bowl, then put the bowl into the pre-dug seedling border pit, then water, cover the 1--2cm fine soil, and finally cover the greenhouse film. After 45 days of age, the seedlings were bagged and transplanted.
