Abstract

The present invention relates to a sugarcane planting zoning method based on a comprehensive suitability index, comprising the following steps: natural climate condition estimation, soil moisture and nutrient condition estimation, sugarcane production potential estimation, and sugarcane planting zoning based on a comprehensive suitability index. On the basis of deep investigation and estimation on natural environment conditions of a sugarcane zone, the present invention performs classified estimation on climate, soil, and sugarcane production potential elements of a sugarcane planting zone by combining technical methods in meteorology, agrology, sugarcane cultivation science, and crop modeling science, and facilitates rational production layout planning and scientific planting of sugarcane by fully using natural conditions, thereby improving the utilization rate of climate and soil resources, reducing costs and improving effectiveness, and promoting the sugarcane industry to stride forward for an overall target of "high production, high sugar content, high efficiency, intensification, ecology, and safety".

Abstract

Disclosed are a double PCR detection method for sugarcane white leaf disease phytoplasma and Xanthomonas albilineans and a primer set thereof. The present invention designs a pair of specific primers for the tuf gene of sugarcane white leaf disease phytoplasma and the rpoD gene of Xanthomonas albilineans, respectively, and by means of optimization, establishes a double PCR reaction system that is capable of simultaneously detecting the sugarcane white leaf disease phytoplasma and the Xanthomonas albilineans.

Abstract

Disclosed is a PCR-RFLP identification method for different subgroups of sugarcane white leaf disease phytoplasma, wherein a tuf gene of a sugarcane white leaf disease phytoplasma is taken as an object for designing specific primers, a tuf gene fragment is obtained by PCR amplification, and a restriction endonuclease Msp I is then used to digest the tuf gene fragment obtained by amplification, and different subgroups of the sugarcane white leaf disease phytoplasma are distinguished by a differentiated RFLP restriction map. Therefore, a sugarcane white leaf disease phytoplasma subgroup 16SrXI-B and a sugarcane white leaf disease phytoplasma subgroup 16SrXI-D can be identified without sequencing.

Abstract

Disclosed is a method for construction of a sugarcane brown rust resistance gene mapping genetic segregation colony. The method comprises: obtaining F1 generation seeds by means of hybridization between sugarcane varieties of different sources with high susceptibility to brown rust as female parents and sugarcane varieties of different sources with high resistance to brown rust and not containing Bru1 genes as father parents; screening true F1 hybrid seeds by means of seeding; planting true F1 hybrid single plants; inoculating brown rust germs; surveying morbidity; evaluating resistance on the basis of 9-level standards; analyzing the inheritance of disease resistance of true F1 hybrid colonies; selecting a true F1 hybrid colony with a segregation ratio of about 3 to 1 as the sugarcane brown rust resistant gene mapping genetic segregation colony. The method according to the present invention has simplified procedure and good operability, the segregation ratio for the constructed true F1 hybrid colony is about 3 to 1, the disease resistance gene is controlled by dominant monogene and can be used for brown rust resistance gene mapping.

Abstract

A method for promoting germination of underground buds and growth of new-born root systems of ratoon sugarcane is to cut stubbles based on a depth survey of the stubbles of the ratoon sugarcane, particularly including steps of: for a ratoon sugarcane field after mechanical harvesting, cutting the stubbles with a sugarcane stubble cutting machine, and remaining underground stubbles of 5-7 cm after cutting; for a ratoon sugarcane field with manual harvesting, cutting the sugarcane with a hoe, and remaining underground stubbles of 10-12 cm after cutting, so as to realize sugarcane cutting and stubble cutting in one step; thereafter, applying fertilizers and pesticides, and hilling up, wherein the underground buds of the stubbles are controlled to be distributed 10-15 cm below ground after hilling up; and finally conducting whole film mulching. The present invention is advanced and practical, and easily used and promoted.

Abstract

A green, sustainable and high-yield planting method for sugarcane, comprising seven steps, as follows: selecting healthy and high-quality sugarcane seeds, digging furrows for sugarcane, scientifically applying fertilizers, planting seeds and covering with soil, covering with film and covering with soil , harvesting the sugarcane and managing perennial roots. Scientific planting and harvesting are strengthened during two key periods of the sugarcane planting and harvesting. During the period of sugarcane planting, the usage amount of chemical fertilizers is reduced, special slow-release fertilizers for the sugarcane are applied and bio-organic fertilizers are supplied, fully-biodegradable mulching films are used to completely cover, and promote the growth of the sugarcane. Concerning the period of sugarcane harvesting, the traditional harvesting method is altered to cut deep into the soil; fertilizers required by the perennial roots of the sugarcane are then directly applied into the furrows, and the soil is dressed and completely covered with a film, so the maintenance of the perennial roots of the sugarcane can be finished. The method realizes the green production of sugarcane, increasing the yield and the sucrose content, reducing the usage amount of chemical fertilizers, increasing the soil fertility and utilization rate, improving the ecological environment of a sugarcane field, promoting the growth of the sugarcane and increasing the income of sugarcane farmers, and is easily popularized and applied.
