Other management are the same as the upper Routine Management of production.
Label and sampling: from April 28th, 2015, every afternoon randomly selected life in the area D and the area X cultivated population respectively The typical single plant of long neat and consistent therefrom selects the female flower of main stem nearly growing point virgin room 2.0~2.5cm of length to carry out listed mark Note, ovary different development stage are indicated with number of days after marking, and are denoted as 1d on the day of label, and so on.Measurement every afternoon mark Remember the ovary length of female flower, records corolla color, it is special according to ' 6457 ' naturally-occurring typical super ovarys and normal ovary feature Property (table 1), respectively the area D and the area X press female flower different development stage to corolla, ovary carry out separately sampled, liquid nitrogen flash freezer, save It is spare in -70 DEG C of refrigerators.
The super ovary of table 1 and normal ovary sampling standard
In table 1, the N-4 in normal ovary developmental stage column refers to the 4th day spent before blooming, and N-3 refers to the 3rd spent before blooming It, and so on;Similarly, the S-8 in column of super ovary development period refer to spend it is in full bloom before the 8th day, S-7 refer to spend it is in full bloom before 7th day, and so on.As known from Table 1, relative to normal ovary developmental stage, super ovary development period, the flowers are in blossom, and the time is bright It is aobvious to delay;And spending for super ovary is obviously bigger than spending for normal ovary;The length of finally obtained super ovary compares normal-sub Room it is bigger.
Cucumber ovary (fruit) and female bud stage corolla length are measured simultaneously, record corolla color.Investigation every morning note The flowering time of record mark female flower is super (normal) by the investigation super ovary incidence of canonical statistics and normal ovary incidence The accumulative number of blooming of ovary incidence=super (normal) ovary/(label female flower number-sampling number) × 100%.Different disposal is to super The influence of grade ovary incidence and normal ovary incidence is as shown in Figure 1.
Period measures plant strain growth gesture (leaf length, leaf width, internode length, stem thickness), specific as shown in table 2.
Record weather condition (fine day, cloudy day, cloudy, rainy day), weather condition spend preceding 8 days institutes with super ovary daily simultaneously Account for percentage expression, fine day rate=fine day number of days/8 day × 100%.Measure the rings such as sunlight room temperature, illumination, relative humidity The border factor, the influence that super ovary and normal ovary occur for analysis environmental factor.It is specific as shown in Figure 2.
Influence of 1.1 different disposals to super ovary incidence and normal ovary incidence
As shown in Figure 1, super ovary induction area (area D) super ovary incidence shows as being gradually increasing from low to high thereafter Downward trend, induction initial stage (4.28-5.3 days) super ovary incidence is lower, average out to 2.8%;Surpass within the 6th day after induction Grade ovary incidence is continuously improved, until 5.15 reach peak, i.e., then super ovary incidence 84.4% declines, it is seen that 5.15 sampling samples are the best samples of the super ovary subsequent analysis in the area D;And the normal ovary hair of normal ovary induction area (area X) Raw rate show as it is overall in the trend that is gradually reduced from high to low, induction initial stage (4.28-5.3 day) normally ovary incidence compared with Height, average out to 96.5%, wherein date 4.30,5.2 normal ovary incidences are 100%, gradually decrease down 73.9% thereafter, because This, determines that the date 4.30,5.2 is that the normal ovary in the area X most preferably samples batch.
1.2 different disposal plant strain growth gesture compare
The area D and the area X plant strain growth gesture are more specific as shown in table 2.
2 area D of table and the area X plant strain growth gesture compare
As shown in Table 2, super ovary induction area (area D) Plant Leaf length, leaf width, leaf area, internode length, stem thickness are respectively than just Normal ovary induction area (area X) increases 16.9%, 27.6%, 49.2%, 7.7%, 24.5%, illustrates ' 6457 ' plant of self-mating system Healthy and strong, growth potential is the necessary condition that super ovary occurs by force, and medium plant strain growth gesture plant on the weak side is easy to produce high ratio The normal ovary of example.
Influence of 1.3 illumination to ovary induction incidence
To be known by Fig. 2, illumination shows opposite trend to the influence that super ovary and normal ovary occur, and fine day rate is high, Super ovary incidence is higher, and the same period normal ovary incidence is lower, and April 28 to May 2, per day fine day rate 55%, surpassed Grade ovary incidence average out to 2.8%, and the same period normal ovary rate average out to 96.5%, wherein April 30 and fine day on May 2 Rate is respectively 63% and 50%, and normal ovary incidence is up to 100%, and super ovary incidence is respectively 1.4% He 1.5%;May 3 to 9 per day fine day rates 42.9%, super ovary incidence average out to 44.5%, and the same period normal ovary rate Average out to 89.2%;May 10 to 16 per day fine day rates 89.3%, super ovary incidence average out to 77.5%, and the same period Normal ovary rate average out to 82.4%, wherein fine day rate 100% on May 15, super ovary incidence reach peak 84.4%, just Normal ovary incidence is only 75.0%.Different weather temperature indoor illumination is different, after measured fine day, in cloudy, rainy days greenhouse most Big intensity of illumination is respectively 30~45,15~20,1~5Klux.As it can be seen that continuous sunny advantageously forms super ovary, illumination is not Foot advantageously forms normal ovary.
In summary, the present invention is changed the incidence of super ovary by cultivation management, environmental condition.The present invention adopts With the cultivation managements mode such as " big hypertrophy water ", " reducing the load of commodity melon " " falling seedling in time ", obtains the best fruiting period super ovary and occur Rate is up to 84.4%.By analyzing best fruiting period environmental factor, it is found that the generation of super ovary is also related with illumination.Sufficient illumination Conducive to more photosynthates are formed, fruits/plant is made to have accumulated more photosynthate.In short, the plant for generating super ovary needs to give birth to Growing way is strong, and a high proportion of super ovary occurs in the period of leaf area 645.5cm2, stem thickness 9.4mm and continuous sunny.
Conversely, normal ovary cultivation management is " appropriateness control fertilizer control water ", " normally adopting melon ", " normally falling seedling " etc..March 21 After field planting, plant strain growth gesture is medium on the weak side at the beginning of 5 months, leaf area 432.6cm2, stem thickness 7.5mm, and illumination is insufficient in addition, so normally Ovary incidence is up to 100%.
