Problems solved by technology
[0004] The technical problem to be solved by the present invention is to overcome the technical defects that cassava planting directly adopts field cuttings in the prior art, resulting in uneven emergence rate, difficult management after cultivation, and low planting survival rate. The purpose is to provide a suitable large-scale Planting and cultivating cassava, especially in mountainous areas and barren slopes, can effectively improve the survival rate of cassava seedlings and produce a seedling transplanting method of cassava with higher economic benefits

Embodiment 1
[0028] Embodiment 1 One of the embodiments of the present invention
[0029] Implementation location: Yuanmou County, Yunnan Province; cassava variety: Huanan 124; the specific implementation steps are as follows:
[0030] 1. Arrangement of nursery grounds
[0031] Select the land with good wind, flatness and drainage and irrigation as the seedling land, and raise the furrow after leveling the land, the height of the furrow is 15cm, the width of the furrow is 8cm, and the length of the furrow is determined according to the terrain and the number of seedlings to be raised;
[0032] 2. Seedling time
[0033] Seedling raising time is selected at the end of the dry season and the coming of the rainy season. The suitable areas for cassava planting in Yunnan are mainly tropical and subtropical dry-hot valleys and mountainous areas. There are obvious dry and wet seasons in the climate characteristics. The dry season When the rainy season is over and the rainy season is coming, the ...
Embodiment 2
[0043] Both Embodiment 2 and Embodiment 3 are embodiments of the present invention. Except that the specific operations listed in Table 1 are different, the rest of the steps are the same as Embodiment 1, and will not be repeated.
Embodiment 4
[0044] Example 4 Control
[0045] The conventional planting method of cassava was used as a control, that is, direct cuttings were used in the field, the cassava seed stems were cut off and placed flat on the border, the row spacing of plants was 0.8×1.0m, the soil was 5-8cm, water was poured enough for rooting, and the seedling height after emergence was 8 Thinning of seedlings was carried out when the seedlings reached 15 cm, and routine management was carried out in the later stage.
[0046] The effect of each embodiment is shown in Table 2.

Abstract
The invention discloses a method for culturing and transplanting a seedling of cassava, which belongs to the technical field of plant cultivation. In the method, the seedling is cultured at the end of a dry season and at the beginning of a rainy season, wherein the furrow height of the cultured seedling is 15 to 20cm and the width of a furrow surface is 8 to 10cm; a seedling culturing material adopts a stem section cuttage propagation method; a stem stick under a branch of the cassava is cut off to form a seed stem, wherein the length of the seed stem is 15 to 20cm and the thickness of the seed stem is 1 to 3cm; a root dipping agent is prepared by mixing 0.5 to 1 kilogram of calcined lime, 0.5 to 1 kilogram of rooting powder and 10 to 20 kilograms of water before cuttage; after dipped into the root dipping agent, the seed stem is inserted into the furrow surface, wherein the distance between every two seed stems is 20 to 25cm; and thoroughly decomposed clear dung water is used for irrigation for one time after 3 to 5 days of the cuttage, the seedling with the height of 8 to 15cm is transplanted. The method has the advantages that average survival rate is up to 92 percent, planting survival rate is 18 percent higher than that of plants by the conventional cultivation method, 300 strips of sprouts are saved in each square hectometer, 20 days of labor force is saved in each square hectometer, operation is simple and convenient and the method is easy to grasp.
Description
technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a seedling raising and transplanting method of cassava. Background technique [0002] Cassava (Manihot esculenta Crantz) is a plant of the Euphorbiaceae (Euphorbiaceae) cassava (Manihot) plant. It is native to the Amazon River Basin in South America. After the end of the 16th century, it gradually spread to other tropical and subtropical regions. ° within the zone. It is mainly distributed between 20° north latitude and 20° south latitude. Cassava is a renewable biological resource, an important energy crop in tropical and subtropical regions of my country, and one of the seven major crops with a global output of over 100 million tons. The development of fuel alcohol has brought rare opportunities for the development of cassava industry. The production of fuel ethanol from cassava, a non-grain crop, plays an important role in the development of biomass en...
