Abstract

A hibernation seedling growing method for potato vines is that potato vines gained in winter are stored to be used for generating sweet potato seeding in the next year. The method comprises 1. preparing sand, 2. cutting vines, and 3. storing the potato vines in sand. The step 1 comprises filtering common yellow sand through a screen to remove large sand particles and impurities, and watering to make the sand disperse after clenched sand is loosened. The step 2 comprises selecting strong vines without frosts and diseases after sweet potatoes are gained in the winter, removing leaves to reserve 1.5 to 3 cm petioles, and cutting the vines every two to three knots. The step 3 comprises bricklaying on the ground or digging a pit in the ground, the length and the width are unlimited, and the depth or the height is 1.2 m. Then the potato vines and sand can be flatwise put in the pit one layer by one layer, 1 cm gaps are kept between vines. The thickness of each sand layer is no less than 5 cm, and the thickness of the uppermost sand layer is greater than 20 cm. In the next spring when sweet potatoes are planted, the potato vines can be taken out for cottage. The potato vines stored in sand have a few new roots already, the potato vines will quickly survive after cottage and can strongly grow up, so the output, per unit area, of sweet potatoes can be raised by 10 to 22 %.

Description

One potato seed rattan hibernation seedling method

Technical field

The invention belongs to Ipomoea batatas production field, particularly a kind of sweet potato vine hibernation seedling method.

Background technology

Due to the growth of world population, the increase of non-farming land, per capita arable land is reduced further, how more by less arable land output people expect grain, consider how to save food simultaneously, the multiplex Ipomoea batatas nursery in our southern area, when all the flowers burst open in the warm spring exactly the excellent Ipomoea batatas of the anosis worm of not damaged of winter results to be stored sth. in a cellar next year, more preferably good Ipomoea batatas buries nursery in the ground.This method takies this coarse cereals of Ipomoea batatas.In order to save this part grain, we adopt potato rattan hibernation seedling method, achieve good effect.

Summary of the invention

Potato rattan hibernation seedling method.Potato rattan hibernation seedling method the potato rattan that autumn gathers in the crops is left to the 2nd year produce Ipomoea batatas seedling.1, standby husky: by common yellow sand screen filtration, to remove bulky grain sand and impurity, watering, humidity is unclamped after clutching with sand and can be scattered for degree.2, cut rattan: in the winter time after sweet potato harvesting, select free of frost, disease-free healthy and strong potato rattan, remove blade, retains 1.5-3 centimetre of petiole, to cut section to one section, 3 joint by every two joints.3, Sha Zang: first lay bricks on ground or dig pit, long and does not widely limit, dark or highly 1.2 meters (depending on the thickness of various places frozen soil layer in winter, being advisable at 5-10 DEG C with storage temperature).Then adopted by potato rattan the method for one deck rattan one deck sand to keep flat in hole, between rattan, stay the gap of 1 centimetre.Every layer of husky thickness is no less than 5 centimetres, and most last layer is husky is thickly no less than 20 centimetres, in its surface cover with plastic film, and the area that frost is heavy, stalks mulching or straw screen or mat again on film.To Ipomoea batatas plantation time spring in next year, potato rattan is tripped out cuttage.Potato rattan hibernation seedling method can save the field management between the occupation of land of potato seed nursery and nursery stage, after the potato rattan taking-up that sand is hidden, had a small amount of new root, during cuttage, stay 1-2 to save under soil, ground is stayed a joint, survive fast after cuttage, growing way is good, and Ipomoea batatas yield per unit area can be made to improve 10-22%.

For making sweet potato vine pass the winter smoothly, the Primary Reference local frost time then, as inventor location Guangxi Luo Cheng, 1980-2010 annual frost is 8.8 days, mainly appears at the 1-3 month, the 11-12 month, the frequency that January occurs is the highest, and the time is the longest, intensity is maximum, is secondly December.First December 8 frost day, February 2 next year latest frost day.Just mean before December 8, potato rattan be carried out hibernation nursery, in order to avoid potato seedling frostbite.

Embodiment

East gate town, Luo Cheng county become lucky dummy as stated above standby husky, cut rattan, Sha Zang.Oneself 1 mu of Ipomoea batatas was cut off December 5 by his family, was imbedded on the husky bed got ready in advance.To Ipomoea batatas plantation time spring in next year, potato rattan is tripped out cuttage by March 21.Potato rattan hibernation seedling method can save the field management between the occupation of land of potato seed nursery and nursery stage, and after the potato rattan taking-up that sand is hidden, had a small amount of new root, survive fast after cuttage, growing way is good, and Ipomoea batatas yield per unit area can be made to improve 16%.

Claims

1. a potato seed rattan hibernation seedling method, it is characterized in that the potato rattan that autumn gathers in the crops is left to the 2nd year produces Ipomoea batatas seedling.

2. a potato seed rattan hibernation seedling method according to claim 1, is characterized in that 1, standby husky: by common yellow sand screen filtration, remove bulky grain sand and impurity, watering, humidity is unclamped after clutching with sand and can be scattered for degree.2, cut rattan: in the winter time after sweet potato harvesting, select free of frost, disease-free healthy and strong potato rattan, remove blade, retains 1.5-3 centimetre of petiole, to cut section to one section, 3 joint by every two joints.3, Sha Zang: first lay bricks on ground or dig pit, long and does not widely limit, dark or highly 1.2 meters; Then adopted by potato rattan the method for one deck rattan one deck sand to keep flat in hole, between rattan, stay the gap of 1 centimetre.Every layer of husky thickness is no less than 5 centimetres, and most last layer is husky is thickly no less than 20 centimetres, in its surface cover with plastic film, and the area that frost is heavy, stalks mulching or straw screen or mat again on film.To Ipomoea batatas plantation time spring in next year, potato rattan is tripped out cuttage.Potato rattan hibernation seedling method can save the field management between the occupation of land of potato seed nursery and nursery stage, after the potato rattan taking-up that sand is hidden, had a small amount of new root, during cuttage, stay 1-2 to save under soil, ground is stayed a joint, survive fast after cuttage, growing way is good, and Ipomoea batatas yield per unit area can be made to improve 10-22%.

3. a potato seed rattan hibernation seedling method according to claim 1, it is characterized in that for making sweet potato vine pass the winter smoothly, the Primary Reference local frost time then, inventor location Guangxi Luo Cheng, first December 8 frost day, just mean before December 8, potato rattan be carried out hibernation nursery, in order to avoid potato seedling frostbite.
