Description

A method for transplanting and false planting of sugarcane detoxified original seedlings

technical field

The invention belongs to the field of plant cultivation, and relates to a method for transplanting sugarcane seedlings, in particular to a method for transplanting sugarcane detoxified original seedlings into sockets.

technical background

Sugarcane (Saccharum officinarum L.) is the most important sugar crop and one of the important raw materials for light industry, chemical industry and energy. China is one of the major sugar producing countries in the world, and sugarcane sugar accounts for about 94% of the total sugar in my country. Therefore, the development of sugarcane production plays an important role in improving the quality of life of the people, promoting the development of agriculture and related industries, and even the development of the entire national economy.

my country's sugarcane is mainly distributed in tropical and subtropical regions south of 24° north latitude, with Guangxi, Yunnan, Guangdong and Hainan provinces as the main production areas. The "Twelfth Five-Year Plan" pointed out that the cultivation area of sugar cane should be stabilized at 29 million mu, and the total output should reach more than 140 million tons, so as to ensure the basic self-sufficiency of domestic sugar consumption.

In the production of sugarcane, asexual reproduction is generally used. After years of planting, it is easily infected by various pathogens, which degrades the species, resulting in a decrease in sugar content and yield of sugarcane. Mosaic disease and perennial root dwarf disease are the most serious pathogens infecting sugarcane, and common physical or chemical methods are difficult to eradicate, which has become the main factor restricting the increase of sugarcane yield and sugar content in my country.

my country's scientific research institutes proposed the use of heat treatment combined with axillary bud meristem culture technology to conduct research on five aspects including comprehensive detoxification of sugarcane stems, rapid propagation without mutations, rapid detection of pathogens, field propagation and supporting cultivation techniques, and the tests showed that the above The detoxified healthy sugarcane seedlings obtained in the steps do not contain pathogenic bacteria, can increase the yield of sugarcane by more than 30%, increase the sugar content by more than 1 percentage point, save 60% of the amount of seeds used, and successfully solve the problems of sugarcane species degradation and breeding of improved varieties in my country technical problems.

At present, most of the conventional ways of transplanting the original seedlings of sugarcane virus-free are carried out in the greenhouse, and the seedlings are raised in plastic bags (bowls) in the shed, and there are also bare-root seedlings in the shed. The advantage is that the original seedlings have a high survival rate. , but the production cost is high and the transportation is difficult, time-consuming and labor-intensive. There are also open-air bare-root transplanting seedlings, which are low in seedling cost, but the root system is vulnerable when transplanted out of the nursery, the survival rate is low when planting in the field, and the seedling slowing period is long, which is not conducive to the development of my country's sugarcane industry.

Contents of the invention

The purpose of the present invention is to provide a method for transplanting the original seedlings of sugarcane detoxified seedlings in plug trays for the deficiencies in the prior art.
