Abstract
A half-cutting method for culturing the seedlings of sweet potato includes such steps as longitudinal cutting a sweet potato to obtain two halves, dipping in plant ash, and burying them underground in an inclined mode. Its advantages are high germinating rate and uniformity, and less consumption of seed sweet potato.
Description
One, technical field
The present invention relates to the Ipomoea batatas culture technique, particularly relate to a kind of by first to cuing open the method for growing seedlings again to the potato seed of Ipomoea batatas.
Two, background technology
It all is that Ipomoea batatas is entirely imbedded in the soil that known Ipomoea batatas is grown seedlings.It is difficult that this seedling method not only causes the Lower Half of Ipomoea batatas to germinate, and reduces emergence rate, the more important thing is a kind of waste to the Ipomoea batatas provenance.
Three, summary of the invention
The invention provides a kind of Ipomoea batatas to cuing open seedling method, with the emergence rate that improves Ipomoea batatas and save potato seed.
The object of the present invention is achieved like this: earlier Ipomoea batatas is done vertically to cuing open before the Ipomoea batatas sowing, with cutting plane in 5 minutes, dip in get newly fire, temperature reduced to the ash below 50 ℃, then cutting plane is upwards placed and shone in the sun 1 hour~2 hours, if meeting the cloudy day then must dry in the air two days, trench digging plantation then, when placing Ipomoea batatas, must section is downward, and allow the head of Ipomoea batatas be lower than afterbody, make the Ipomoea batatas section become 25 degree~30 degree with the angle of horizontal plane, behind the earthing, the Ipomoea batatas afterbody is apart from ground 3cm~5cm.
Adopt such scheme can receive following remarkable result:
1, owing to eliminated the germination dead angle of Ipomoea batatas lower surface in the conventional cultivation fully, the product seedling rate of its seedling is improved more than 30%, this will save a large amount of potato seeds.
2, the cutting plane with Ipomoea batatas dips in ash and the airing certain hour of newly firing, and can avoid wound infection fully.
3, because the bud mouth of Ipomoea batatas head is easy to germinate, the difficulty and the bud mouth of afterbody not only germinates, and germinating time evening, the seedling that grows is thin and delicate, after yet the inclination under tail the higher authorities of employing this programme is placed, the distribution of the auxin concentration in the Ipomoea batatas body changes, make time retardation that head germinates and the germinating time of afterbody ahead of time, simultaneously, the nutrition supply of head bud mouth is suppressed, and the nutrition supply of afterbody bud mouth improves, and finally reaches the germinating time of each bud mouth of head and the tail, strengthening of young plant, a little less than all reach unanimity, not only make the Ipomoea batatas germination rate reach highest level, and improved the uniformity of seedling.
Claims (1)
1, a kind of Ipomoea batatas is to cuing open seedling method, it is characterized in that: before the Ipomoea batatas sowing, earlier Ipomoea batatas is done vertically to cuing open, with cutting plane in 5 minutes, dip in get newly fire, temperature reduced to the ash below 50 ℃, then cutting plane is upwards placed and shone in the sun 1 hour~2 hours, if meeting the cloudy day then must dry in the air two days, trench digging plantation then, when placing Ipomoea batatas, must section is downward, and allow the head of Ipomoea batatas be lower than afterbody, make the Ipomoea batatas section become 25 degree~30 degree with the angle of horizontal plane, behind the earthing, the Ipomoea batatas afterbody is apart from ground 3cm~5cm.
