Embodiment 1

[0019] (1) Test time and place

[0020] The experiment was carried out in Cucumber Garden Town, Yuanmou County, Chuxiong Prefecture from March to June 2011. The soil was red loam with medium fertility.

[0021] (2) The steps of the method for raising sweet potato drought-resistant seedlings are the same as those described in the summary of the invention.

[0022] (3) Effect of film-covering and soil-covering seedling cultivation on sweet potato emergence and seedling growth

[0023] After sowing, the ground temperature and soil water content were measured in March, and the plant height and stem diameter were measured after the seedlings were ready. It can be seen from Table 1 that the film-covered soil has a temperature-increasing effect. Compared with the ordinary film-covering method, it can avoid the high temperature inside the film at noon and has a certain cooling effect. It can be seen from Table 2 that both the film-covering soil seedling cultivation and the common fi...

Embodiment 2

[0033] (1) Test time and place

[0034] From March to June 2012, it was carried out in Yuanma Town, Yuanmou County, Chuxiong Prefecture. The test site was red loam soil with medium fertility.

[0035] (2) The steps of the method for raising sweet potato drought-resistant seedlings are the same as those described in the summary of the invention.

[0036] (3) Effect of film-covering and soil-covering seedling cultivation on sweet potato emergence and seedling growth

[0037] After sowing, the ground temperature and soil water content were measured in March and June respectively, and the plant height and stem diameter were measured after the seedlings were ready. It can be seen from Table 4 that the film-covered soil has a temperature-increasing effect. Compared with the ordinary film-covering method, it has a certain cooling effect when the temperature is high at noon. It can be seen from Table 5 that both the film-covering soil and the common film-covering method have good wa...

Abstract

The invention relates to a drought-resisting batata seedling culture method, and belongs to the technical field of seedling culture. The method includes the steps of seedling bed selection, seed batata selection and treatment, seeding, film mulching and soil covering, and seedling bed management. After batata seeding, seed batatas are covered with soil of 2-3cm, preferably not exposed, thoroughly watered and mulched with a film, and then the mulching film is covered with a layer of 3-5cm thick soil completely. The drought-resisting batata seedling culture method has the advantages of simplicity, fast batata seedling emergence, seedling emergence orderliness, strong seedlings and good drought-resisting effect.

Description

Technical field: [0001] The invention relates to a method for raising sweet potato drought-resistant seedlings, which belongs to the technical field of seedling raising. Background technique: [0002] Sweet potato (Ipomoea batatas L.), also known as sweet potato, sweet potato, sweet potato, sweet potato, etc., is an annual herb of the genus Ipomoea in the family Convolvulaceae. my country is the country with the largest sweet potato cultivation area and the largest output in the world. Sweet potato is one of the main food crops in my country and Southwest China. Sweet potato has high nutritional value. The potato chips are rich in starch, soluble sugar, protein and multivitamins. Sweet potatoes have high and stable yields, wide adaptability, drought and barren resistance, strong stress resistance, and a wide range of uses. They are not only edible, medicinal, and feed crops, but also industrial raw material crops such as starch, alcohol, and sugar. Temperature and moisture ...
