Problems solved by technology

[0003]Currently, the common cultivation methods to increase cassava production in production are: planting high-yielding fine new varieties and increasing fertilizer application, but the yield increase of these two methods is very limited. Generally, it only reaches 10-30%, and increases the input cost

Embodiment Construction

[0016] The cultivation technology of high-yield cassava is realized through the following steps.

[0017] 1. The planting land is dry land, which is easy to drain and does not cause soaking. The soil has a large sand content and is soft, which is conducive to harvesting and picking cassava.

[0018] two, Deep plowing and land preparation, adequate base fertilizer application , cassava is easy to plant and does not require high soil conditions, but cassava is a deep-rooted crop, and it is easier to obtain high yields after deep plowing. Generally, deep plowing with a broken rake is required, and the deep plowing is 27~30 cm. The furrow method cultivates thick soil. The height and width of the furrow should be determined according to the terrain, soil quality and climate. Generally, the width of the furrow is 0.9 meters, the width of the furrow is 0.3 meters, and the height of the furrow is 25 to 35 centimeters. The furrow surface with good drainage can be appropriately widen...

Abstract

The invention provides a high-yield cassava cultivation technology. The high-yield cassava cultivation technology is characterized in that firstly, the planting land is a dry land; secondly, deep ploughing and soil preparation are conducted, and base fertilizer is applied sufficiently; thirdly, good varieties are selected and used; fourthly, thick seed stems are selected and used as cuttage seeds, wherein the seed stems should have vitality and are cut off to be 10-15 centimeters long, and the cut seed stems are soaked in ambam or lime water for disinfection; fifthly, planting is conducted at proper time, wherein when the daily average temperature is above 15 DEG C, planting can be conducted, and manure is applied and buried between every two seed stems; sixthly, growing period management includes filling of the gaps with seedlings, thinning, weeding and after-manuring; seventhly, pest control is conducted, wherein bisultap or carbofuran and fine soil are mixed and applied, or methamidophos is used for trapping and killing pests, and application of the fertilizer is stopped two months before harvesting; eighthly, harvesting is carried out at proper time in autumn, and the root yield and starch content will be lowered if harvesting is conducted too early or too late.

Description

technical field [0001] The invention relates to a method for cultivating crop cassava and belongs to the field of agricultural technology. Background technique [0002] Cassava is an erect subshrub. The plant height is 1.5-3m. The root tubers of the original species are cylindrical, fleshy and rich in starch. The leaves are alternate, 10-20cm long, palmately 3-7 deeply lobed or totally lobed, and there is a large area of ​​white or yellow markings in the center of the agricultural green leaves. Cassava was first cultivated in Gaozhou, Guangdong Province, and then introduced to Hainan Island. It is now widely distributed in southern China, Fujian, Yunnan, Jiangxi, Sichuan and Guizhou. [2] There are more than 150 species of cassava (Manihat spp), including cultivated species and wild species, among which cassava (Manihat esculenta Crantz) is the only species used for economic cultivation, and it is the only cassava species that can harvest products in production planting; C...
