Description
Technical field
The present invention relates to plant variety screening technique fields, and in particular to a method of screen drought-enduring melon variety.
Background technique
Muskmelon, also known as " muskmelon " are the annual herbaceous plant of Curcurbitaceae Cucumis, leaf heart shape；Flower unisexuality, it is yellow
Color, monoecism, or be hermaphrodite flower；Melon is in ball, ovum, ellipse or oblateness, and color of the leather is yellow, white, green or miscellaneous have various speckles；Pulp
Green, white, crimson or orange-yellow, meat is crisp or soft, and taste is fragrant and sweet tea.Property pyrophilous, dry and sufficient sunlight.The torrid zone is originated in,
China is generally cultivated various regions, various types, and the fragrant and sweet taste that North China, northwest produce is dense, and the moisture multi-flavor that is produced from humid area is thin, is the summer
One of the excellent fruit in season.Muskmelon is a kind of important gourd vegetable crop, arid season or Arid&semi-arid area often
There are drought stresses, can seriously affect the production of muskmelon.Therefore, the drought resistance for improving crop varieties, have become arid and
The key subjects of semiarid zone agricultural research；And accurately have both the drought resistance of crop varieties, be cultivate drought-resistant variety must
Want basis.Drought resisting identification is exactly the process screened, evaluated and sorted out by the drought-resistant ability size of crop varieties；Pass through drought resisting
High-quality germplasm can be provided for Drought-resistant Breeding by identifying.Although different researchers are studied work to the drought resisting of muskmelon from many aspects
Make, has carried out beneficial discussion for understanding muskmelon drought resistance, but the screening of existing drought-enduring melon variety has accurately low lack
Point, lacks that a kind of planting environment is easy to control, method easy to operate and high accuracy drought-enduring melon variety.
Summary of the invention
For the defects in the prior art, the present invention provides a kind of method for screening drought-enduring melon variety, the screening technique
At low cost, drought-enduring accuracy in detection is high, and detection cycle is short, easily operated, convenient in each local promotion and implementation.
To achieve the above object, technical solution provided by the invention are as follows:
The present invention provides a kind of method for screening drought-enduring melon variety, comprising steps of step S1, selected full seed,
Uniformity, disease-free muskmelon seeds carry out disinfection, and are after planting covered later with matrix in cultivation bed with broadcast mode sowing；
Etc. muskmelon seedlings thinning is carried out when growing to 21 heart of leaf, choose the consistent strong seedling of growing way, each cultivation bed stays 50 plants of muskmelon seedlings；Its
In, matrix is organic ecological cultivation matrix or soil matrix；The relative humidity control of matrix is 75%；Step S2, by muskmelon seedling
It is divided into 2 groups of Osmotic treatment group, 1 group of control and control；Osmotic treatment group is planted using organic ecological cultivation matrix, etc. muskmelon seedlings it is raw
Osmotic treatment is carried out when length to 51 heart of leaf, the relative humidity staged of matrix is down to 30%, and maintains several days of arid；Control 1
Group is planted using organic ecological cultivation matrix, and the relative humidity of matrix is maintained 75% always；2 groups are compareed using soil matrix kind
It plants, the relative humidity of matrix is maintained 75% always；Step S3 counts 2 groups of Osmotic treatment group, 1 group of control and control respectively
The lateral root number of every plant of muskmelon seedling, the average value of 50 plants of muskmelon seedling lateral root numbers is the cultivation bed muskmelon seedling in single cultivation bed
Lateral root number, the average value of the muskmelon seedling lateral root number of every group of corresponding multiple cultivation beds are the muskmelon seedling lateral root number of the group
Amount；Step S4 calculates each melon variety drought-resistant ability value, and drought-resistant ability value is bigger, illustrates corresponding melon variety drought-resistant ability
It is stronger；Single melon variety drought-resistant ability value=(the kind Osmotic treatment group is with respect to lateral root number/all identification of species arid
Processing group is with respect to the average value of lateral root number) × (the kind Osmotic treatment group is opposite with respect to lateral root number/1 group of varietal check
Lateral root number)；Wherein, Osmotic treatment group is right with respect to lateral root number=Osmotic treatment group lateral root number/2 groups of control lateral root number
According to 1 group of opposite 1 group of lateral root number=control, 2 groups of lateral root number/control lateral root number.It should be noted that for drought-resistant ability
The accuracy of identification is caused when single melon variety drought-resistant ability value calculates using relative value to exclude cultivation matrix
Background interference.
Preferably, in step S1, the raw material components of organic ecological cultivation matrix include corn stover, decomposed cow dung, rice husk,
Clinker and wormcast；Organic ecological cultivation matrix is decomposed using primary fermentation.
It is further preferred that in step S1, corn stover, decomposed cow dung, rice husk, clinker and wormcast mass ratio be 2:
4:1:3:3.
Preferably, in step S1, added with 1g carbendazim in every 10L organic ecological cultivation matrix.
Preferably, in step S1, the physicochemical property of organic ecological cultivation matrix includes: that bulk density is 0.73g/cm3, total pore space
Degree is 88%, ventilating slit 22%, and water holding hole is 66%, pH value 6.6, conductivity 3.16ms/cm, cation exchange
Amount is 71cmol/kg.
Preferably, entire screening process carries out in intelligent greenhouse, and greenhouse air relative humidity remains 55%, warm round the clock
Degree is 25/17 DEG C.
Preferably, in step S1, a length of 100cm, width 50cm, the depth 50cm of cultivation bed.
Preferably, in step S1, the cladding thickness of matrix is 0.6~0.8cm, preferably 0.7cm.
Preferably, in step S2,2 groups of Osmotic treatment group, 1 group of control and control respectively include three cultivation beds.
Preferably, in step S2, several days are 15 days.
Technical solution provided by the invention, have it is following the utility model has the advantages that
(1) for plant, the development degree of underground root system determines the power of drought-resistant ability；Intend according to underground root system
Development degree identify the drought resistance of kindred plant different cultivars, but the development degree of root system is affected by matrix.It plants
Training discrete phase is more suitable for the growth of root system of plant for soil, for example cultivation matrix total porosity is bigger than soil matrix.For
The growing environment built to root system, it is necessary first to develop and a be suitble to the cultivation of plants matrix.The present invention passes through research
Influence of the different formulations matrix to muskmelon growth potential, plant Photosynthetic Index, root system, yield and quality, it is determined that the organic life of muskmelon
The most adaptation side of state cultivation matrix, good using the cultivation matrix one side plant growing way compared with field planting, yield and quality
It is promoted, on the other hand can reduce the use of chemical fertilizer, pesticide, water-saving fertilizer-saving.
