The invention relates to a sugarcane hybrid parent root-promoting nutrient and a root-promoting method thereof, wherein the root-promoting nutrient consists of a white root growth-promoting fertilizer, a calcium fertilizer absorption promoter, a trace element fertilizer, a frostbite protective agent, a root rot protective agent and a base fertilizer containing nitrogen, phosphorus and potassium; the root promoting method comprises the following steps: (1) phimosis, (2) conservation, (3) light treatment, and (4) hybridization; the method solves the problems of poor rooting effect, long consumed time, underdeveloped root system growth and the like in the prior art, can increase white roots, plays a role in promoting roots and strengthening seedlings, has sufficient nutrient supply, and ensures that sugarcane parents have long survival time and good seed quality.
Description
Technical Field
The invention relates to the technical field of planting of sugarcane hybrid parents, in particular to a root promoting nutrient for the sugarcane hybrid parents and a root promoting method thereof.
Background
Sugarcane, sugarcane genus, perennial big solid herbs. The root is strong and developed. The height of the stalk is 3-5(-6) m. Taiwan, Fujian, Guangdong, Hainan, Guangxi, Sichuan, Yunnan and other tropical areas in south China. The sugarcane is suitable for being planted in places with fertile soil, sufficient sunlight and large temperature difference in winter and summer. Sugar cane is a temperate and tropical crop, a raw material for sucrose production, and ethanol can be extracted as an energy substitute. The sugarcane contains rich sugar and water, also contains various vitamins, fat, protein, organic acid, calcium, iron and other substances which are very beneficial to the metabolism of a human body, is mainly used for preparing sugar, and the epidermis is generally purple and green with two common colors, namely red and brown, but is rare.
The hybrid parent generally refers to male and female individuals selected when animals and plants are hybridized. The sugarcane hybrid parent refers to male and female individuals selected during sugarcane hybridization; the sugarcane hybrid parents need to be selected, and besides the characters of the male parent and the female parent are complementary, plants selected as the male parent and the female parent need to be free of diseases and harm and have good growth vigor. After the sugarcane blooms, the success of hybridization is ensured, the quality of hybrid seeds is improved, and the method is the basis of sugarcane hybrid seed production. Problems in the current hybridization process are: after the hybrid parents bloom, the hybrid parents need to be transferred into a greenhouse for hybridization, but the operation is difficult if the hybrid parents are dug out with roots. At present, the middle and lower parts of sugarcane stalks of sugarcane parents are wrapped by nutrient soil, after the parts grow roots, the parts are cut off and then transferred into a greenhouse for hybridization, and the parents are required to survive for more than one week to ten days. However, the conventional nutrient soil for phimosis has poor rooting effect, long time consumption and underdeveloped root growth.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a sugarcane hybrid parent root-promoting nutrient with high white root growth, root and seedling promotion and high popularization value and a root-promoting method thereof.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows: the root promoting nutrient for the hybrid sugarcane parents consists of the following components in percentage by weight: 5-10% of white root growth promoting fertilizer, 1-3% of calcium fertilizer absorption promoter, 1.5-5% of trace element fertilizer, 3-5% of frostbite protective agent, 0.01-0.03% of root rot protective agent and the balance of base fertilizer containing nitrogen, phosphorus and potassium;
the white root growth promoting fertilizer comprises the following components in parts by weight: 35-40 parts of calcium sulfate, 12-15 parts of sugar alcohol calcium and 10-14 parts of calcium nitrate; 12-15 parts of a magnesium fertilizer; 7-10 parts of a zinc fertilizer;
the calcium fertilizer absorption enhancer comprises the following components in parts by weight: 20-30 parts of carbon powder; 5-8 parts of vermiculite powder; 25-30 parts of tourmaline powder;
the frostbite protective agent is bamboo powder;
the root rot protective agent comprises the following components in parts by weight: 20-25 parts of needle mushroom residues; 1.5-1.8 parts of strigolactone.
