Embodiment 1
[0026] A method for planting cassava in advance, comprising the steps of:
[0027] (1) Stem girdling: It is required to select mature and excellent seed stems free from diseases and insect pests. The length of the cassava seed stem is 20cm, and there are ≥6 bud eyes. All the phloem of the stem is girdled in the middle, with a width of 1cm;
[0028] (2) Growing seedlings in greenhouses: On February 1 of each year, when the highest temperature was below 8°C, adopt greenhouse seedlings; the cassava seed stems that were girdled were planted in greenhouses, and the light transmittance of greenhouses was more than 50%. Temperature treatment, the temperature in the shed is required to be ≥15°C during the day, preferably controlled at 20°C, not lower than 10°C at night, and the temperature in the whole day is not higher than 30°C;
[0029] (3) Transplanting in the greenhouse: plant cassava in a container with a length of 40 cm, a width of 15 cm, and a height of 15 cm, fill the contain...
Embodiment 2
[0039] A method for planting cassava in advance, comprising the steps of:
[0040] (1) Stem girdling: It is required to select mature and excellent seed stems free from diseases and insect pests. The length of the cassava seed stem is 22cm, and there are ≥6 bud eyes. All the phloem of the stem is girdled in the middle, and the girdling width is 1cm;
[0041] (2) Growing seedlings in greenhouses: In the first ten days of February every year, when the highest temperature is below 8°C, adopt greenhouse seedlings; plant cassava seed stems that have been girdled in greenhouses, and the light transmittance of greenhouses is above 50%. For treatment, the temperature in the shed is required to be ≥15°C during the day, preferably controlled at 20°C, not lower than 10°C at night, and the temperature in the whole day is not higher than 30°C;
[0042] (3) Transplanting in the greenhouse: plant cassava in a plastic container with a length of 40 cm, a width of 15 cm, and a height of 15 cm, ...
Embodiment 3
[0050] A method for planting cassava in advance, comprising the steps of:
[0051] (1) Stem girdling: It is required to select mature and excellent seed stems free from diseases and insect pests. The length of the cassava seed stem is 20cm, and there are ≥6 bud eyes. All the phloem of the stem is girdled in the middle, with a width of 1cm;
[0052] (2) Greenhouse seedling cultivation: In mid-February every year, when the highest temperature is below 8°C, adopt greenhouse seedling cultivation; the cassava seed stems that have been girdled are planted in a greenhouse, and the light transmittance of the greenhouse is above 50%, after heating For treatment, the temperature in the shed is required to be ≥15°C during the day, preferably controlled at 20°C, not lower than 10°C at night, and the temperature in the whole day is not higher than 30°C;
[0053] (3) Transplanting in the greenhouse: plant cassava in a container with a length of 40 cm, a width of 15 cm, and a height of 15 cm...
