Problems solved by technology

[0003] Plant growth is inseparable from temperature, and temperature is an important factor affecting the formation of flower organs. However, there is no report on increasing the female flowers of bitter gourd by temperature treatment at the seedling stage in production. The defects of late growth and reduced number of female flowers in the early stage of high temperature cultivation provide a way to reduce the node position of female flowers through low temperature regulation at the seedling stage, increase the rate of female flower nodes, and then increase the early yield. It is suitable for open field soil cultivation, and the operation is simple and convenient, and the effect significantly

Embodiment 1

[0017] Embodiment 1 sowing seedling raising and low temperature treatment at seedling stage

[0018] On June 10, 2015, the bitter gourd seeds for testing were taken, and after accelerated germination, they were sown in seedling trays, and when they grew to 3 true leaves, they were transferred to laboratory light incubators for different temperature treatments. The experiment set up 5 treatments and control CK (data from facility cultivation). The temperature treatment gradient is: 15-29°C temperature treatment, CK: 26°C, the whole photoperiod is set to 8h light and 16h dark, and the light intensity is 100umol m -2 ·S -1 , each treated 50 trees, and planted in the field after 28 days of treatment, and other managements were performed according to conventional management methods.

[0019] After 28 days of processing, transplant the field, observe and count the gender performance of the plants after different temperature treatments and the first female and male flower node posi...

Embodiment 2

[0025] Embodiment 2 sowing seedling raising and low temperature treatment at seedling stage

[0026] On June 10, 2015, the bitter gourd seeds for testing were taken, and after germination, they were sown in seedling trays, and when they grew to 4 true leaves, they were transferred to the laboratory light incubator for different temperature treatments. The experiment set up 5 treatments and control CK (data from facility cultivation). The temperature treatment gradient is: 15-26°C, the whole photoperiod is set as 8h light and 16h dark, and the light intensity is 300umol m -2 ·S -1 , each treated 50 trees, and planted in the field after 28 days of treatment, and other managements were performed according to conventional management methods.

[0027] After 28 days of processing, transplant the field, observe and count the gender performance of the plants after different temperature treatments and the first female and male flower node position of the single plant after the seedli...

Abstract

The invention discloses a method for promoting balsam pear to flower in advance. The method includes: transferring balsam pear seedlings in a three-leaf-one-core stage or four-leaf-one-core stage to an illumination cultivation box to perform illumination treatment for 25-30 days at the cultivation temperature of 17-23 DEG C; and then normally transplanting the balsam pear seedlings. The illumination treatment method includes: alternatively performing illumination for 8 hours and dark treatment for 16 hours, wherein the illumination intensity is 100-300 umol.m<-2>.S<-1>. According to the technical scheme, the first 35 female flower bud rate of the balsam pear is remarkably higher than that of a contrast, a first female flower bud position and a first male flower bud position can be remarkably lowered, and then early flowering of the balsam pear can be promoted.

Description

technical field [0001] The invention belongs to the field of plant planting, and in particular relates to a method for promoting early flowering of bitter melon. Background technique [0002] Bitter melon is a plant of the genus Momordica in the family Cucurbitaceae, and is a common vegetable widely grown all over the world. The high temperature in summer and autumn in southern my country, the late growth of female flowers and the reduction of female flowers of bitter gourd are important reasons for the reduction in early cultivation. It is generally believed that Cucurbitaceae vegetables promote female flower differentiation under low temperature conditions, and high temperature promotes male flower differentiation. The sexual differentiation process of bitter melon is the process of transforming from bisexual flowers to unisexual flowers. Under natural conditions, the number of male flowers of bitter melon plants is significantly greater than the number of female flowers...
