Effect test

Embodiment 1

[0031] This test examines the effect of the lighting distance and lighting time of incandescent lamps on the temperature and humidity inside the carton. The lighting distance is set to 10cm, 20cm, and 30cm respectively, and the temperature and humidity are measured every 0.5h. A temperature and humidity meter is placed in the middle and four corners of the bottom of the carton. It can be seen from Table 1 that incandescent lighting has the functions of heating and dehumidification. The shorter the lighting distance, the higher and faster the temperature inside the carton, and the higher the humidity. When the distance is 30cm, the heat and air humidity in the carton are relatively uniform. After 2.5 hours of lighting, a stable small ecosystem with a temperature of 28°C and a humidity of 44% has formed inside the carton.

Embodiment 2

[0036] This experiment examines the effect of lighting distance on pollen viability. The incandescent lamp and the carton were implemented in the same way as Case 1, and the test pollen was chilli pepper pollen with 85% vigor preserved in the freezer. The distance between the bulb and the pollen is 10cm, 20cm, and 30cm, respectively, ck is without lighting treatment, and other settings are the same. The lighting time was 3h, and the pollen viability was measured after 3h. The pollen viability was detected by TTC staining. Each treatment was repeated three times. The test results show that the 40-watt bulb illuminates for 3 hours, and the safety distance is more than 30cm, which can be satisfied by the height of the commonly used carton.

[0038]

Embodiment 3

[0040] This experiment examines the effects of the temperature generated by the duration of incandescent lighting on the effect of anther pollination and on the viability of pollen. The incandescent lamp is a common 40-watt light bulb in the market, the pollen has just been released from the anther, and the volume of the carton is 44×28×32cm. The distance between bulb and pollen is 30cm. The pollen viability was detected by TTC staining. Each treatment was repeated three times. The experimental results show that when the distance between the bulb and the pollen is 30cm, increasing the lighting time does not increase the temperature in the box, the pollen rate is over 90% within 24 hours, and the pollen viability does not change significantly.

Abstract

The invention provides a method for acquiring pepper pollen. The method comprises the steps of 1) collecting pepper male flowers which have whitish buds and do not bloom; 2) picking anthers off the pepper male flowers; 3) acquiring pollen from the anthers via a pollen collecting box: placing the anthers in the pollen collecting box, closing the box body, and keeping the box body at a proper temperature and humidity to promote the anthers to scatter pollen; 4) taking out a paper sheet, sieving a mixture on the paper sheet and obtaining the pepper pollen. With the method, high quality pepper pollen can be obtained and high yield of pepper pollen can be guaranteed; the method solves the problems of insufficient pollen production and reduction of pollen viability caused by technical restriction and weather influence in conventional pepper hybrid seed production.

Description

technical field [0001] The invention relates to a method for obtaining pepper pollen, in particular to a design of a pollen collection box and a method for efficiently obtaining pepper pollen through the designed pollen collection box, belonging to the technical field of pepper hybrid seed production. Background technique [0002] In the production process of pepper hybrids, the factors that affect the quantity and quality of pollen are: parental sterility in flowering period, unbalanced planting ratio, rainy weather, and poor pollen production technology. Insufficient quantity and poor quality of pollen will lead to a decrease in the yield of hybrid seeds, an increase in cost, and a reduction or loss in the profits of seed producers and seed producers, further weakening the market competitiveness of varieties and enterprises. Therefore, it is necessary to study the efficient preparation method of pepper pollen. [0003] The plant pollen preparation method generally include...
