Problems solved by technology

In the past, cassava breeding institutions in various regions of my country mainly obtained hybrid seeds from the International Tropical Agriculture Center and Thailand. However, this kind of off-site breeding mainly uses local excellent varieties as the parents, but there are regional differences in varieties. Cassava varieties may not perform well in China. This kind of off-site breeding has led to low hybrid breeding efficiency; It has become an urgent task to find a cassava hybrid breeding method that is widely suitable for cassava planting areas in my country.

Embodiment 1

[0062] The cassava flowering control technology of the present invention comprises the following technical steps:

[0063] (1) Site selection and preparation

[0064] ① Leveling. Choose land that is not too barren, with little gravel, no water, sheltered from wind, or protected by forest sections. Plant it from early March to early April. Deep plow and fine harrow 1-2 months before planting, so that The sun fully exposes the land to the sun, sterilizes and levels the land;

[0065] ② Ditching. Ditching according to the row spacing between plants, plowing soil depth of 30-40cm, ditching depth of 20-25cm, spacing between plants and rows at 0.8×0.8m, and furrowing at a row spacing of one meter;

[0066] 3. application of basal manure. Described basal manure is the ternary compound fertilizer that per mu consumption is 500-800kg farmyard manure, 10-12kg urea and 20-25kg NPK concentration ≥ 40%, fully mixes, and basal manure is applied in the middle of furrow Mix well with the so...

[0087] ② Ditching. Ditch according to the distance between plants and rows, the plow soil depth is 30-40cm, the depth of ditching is 20-25cm, the distance between plants and rows is 0.8-0.9×0.9m, and the row spacing is one meter;

[0088] 3. application of basal manure. Described basal manure is the ternary compound fertilizer that per mu consumption is 500-800kg farmyard manure, 10-12kg urea and 20-25kg NPK concentration ≥ 40%, fully mixes, and basal manure is applied in the middle of furrow Mix well wi...

Embodiment 3

[0106] The cassava flowering control technology of the present invention comprises the following technical steps:

[0107] (1) Site selection and preparation

[0108] ① Leveling. Choose land that is not too barren, with little gravel, no water, sheltered from wind, or protected by forest sections. Plant it from early March to early April. Deep plow and fine harrow 1-2 months before planting, so that The sun fully exposes the land to the sun, sterilizes and levels the land;

[0109] ② Ditching. Ditch according to the row spacing of plants, plow soil depth of 30-40cm, ditch depth of 20-25cm, and row spacing of 0.7-0.8×1.0m, and furrow according to row spacing of one meter;

[0110] 3. application of basal manure. Described basal manure is the ternary compound fertilizer that per mu consumption is 500-800kg farmyard manure, 10-12kg urea and 20-25kg NPK concentration ≥ 40%, fully mixes, and basal manure is applied in the middle of furrow Mix well with the soil, cover the furrow ...

Abstract

The invention belongs to the technical field of crop cultivation, and particularly relates to a cassava blossoming regulation and control technology. The cassava blossoming regulation and control technology is characterized by comprising selection and preparation of land, plantation management, regulation and control of the blooming period, flower retention, regulation and control of the ratio of female flowers to male flowers, measurement of the pollen activity, pollination experiment and cross breeding. Stable and superior hybrid seeds are obtained by adopting a chemical regulation and control method and a manual agricultural measure regulation and control method. The cassava blossoming regulation and control technology has the characteristics of early blossoming time, high blossoming rate and easiness in technical operation, and is suitable for cross breeding in most cassava planting areas in China.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a cassava flowering regulation technology. Background technique [0002] Cassava (Cassava) is a shrub-like perennial crop, one of the world's three largest tubers, and is widely cultivated in tropical and subtropical regions. In the subtropical region of my country, cassava is the fifth largest crop after rice, sweet potato, sugar cane and corn. It plays an important role in crop layout, feed production, industrial application, etc., and has become a widely planted crop mainly for processing starch and feed. Cassava is the root of Euphorbiaceae cassava. The cassava root is conical, cylindrical or spindle-shaped, fleshy and rich in starch. Cassava flour is of good quality and can be used for food, or for industrial production of alcohol, fructose, glucose, etc. [0003] At present, in terms of cassava planting, hybrid breeding is a widely used breeding meth...
