Problems solved by technology

[0003] So far, there are only relevant studies reporting the pollen activity and characteristics of Diana polyphylla, as well as the research on its pollination characteristics, and the sample size is not large, so it cannot fully explain the relationship between artificial pollination and seed setting rate.
In the prior art, there is no report about improving the seed-setting rate of Parisia dianthus through artificial pollination, and this technology has certain innovation and promotion value

Embodiment 1

[0020] A method for increasing the fruit-setting rate of P. diaphyllum comprises the following steps:

[0021] (1) Select a strong plant with no pests and diseases, and after the plant blooms, select most of the anther sacs to crack and collect pollen on the second day;

[0022] (2) Use a portable vacuum cleaner to collect mature and full pollen clusters on a polypropylene filter membrane with a diameter of 10mm and a pore size of 450nm;

[0023] (3) Three days after most of the pollen sacs cracked, artificial pollination was carried out, and the collected pollen was dipped with a brush or a soft brush, and evenly spread on the stigma of Dianzhonglou, twice on each stigma; artificial pollination was selected at 4 p.m. Between 1:00 and 8:00 p.m., the artificial pollination was completed within the same day; the next day, in the same way, artificial pollination was performed again.

Embodiment 2

[0025] A method for increasing the fruit-setting rate of P. diaphyllum comprises the following steps:

[0026] (1) Select a strong plant with no pests and diseases, and after the plant blooms, select most of the anther sacs to crack and collect pollen on the third day;

[0027] (2) Use a portable vacuum cleaner to collect mature and full pollen clusters on a polypropylene filter membrane with a diameter of 10mm and a pore size of 450nm;

[0028] (3) Three days after most of the pollen sacs cracked, artificial pollination was carried out, and the collected pollen was dipped with a brush or a soft brush, and evenly spread on the stigma of Dianzhonglou, each stigma 3 times; artificial pollination was selected at 4 p.m. Between 1:00 and 8:00 p.m., the artificial pollination was completed within the same day; the next day, in the same way, artificial pollination was performed again.

Embodiment 3

[0030] A method for increasing the fruit-setting rate of P. diaphyllum comprises the following steps:

[0031] (1) Select a robust plant without pests and diseases, and after the plant blooms, select most of the pollen sacs to crack and collect pollen within the third day;

[0032] (2) Use a portable vacuum cleaner to collect mature and full pollen clusters on a polypropylene filter membrane with a diameter of 10mm and a pore size of 450nm;

[0033] (3) Three days after most of the pollen sacs cracked, artificial pollination was carried out, and the collected pollen was dipped with a brush or a soft brush, and evenly spread on the stigma of Dianzhonglou, twice on each stigma; artificial pollination was selected at 4 p.m. Between 10:00 and 8:00 p.m., artificial pollination is completed within the same day.

[0034] Prove the beneficial effect of the technology of the present invention below by concrete test example:

Abstract

The invention discloses a method increasing Paris polyphylla var yunnanensis maturing rate. The method comprises the following steps of (1) selecting strong and free of insect diseases paris polyphylla var yunnanensis plants, collecting pollen from most plants with cracked pollen sacs after the plants blossoms, (2) utilizing a portable dust collector to collect thoroughly-grown and rich pollen groups to a polypropylene filtration film with the diameter of 10mm and an aperture of 450nm, (3) conducting hand-pollinating three days after most pollen sacs crack, dipping the collected pollen via a writing brush or a soft brush and then evenly coating the pollen on the Paris polyphylla var yunnanensis necking head. Each necking head is dipped for two times; hand-pollination can be conducted from 4pm to 8pm and finished on the day; the next day, the same operations are conducted; and hand-pollination is conducted once more. Paris polyphylla var yunnanensis maturing rate can be improved by more than 40%, so seed source is enlarged for agricultural production and higher promotion value can be achieved.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for increasing the seed-setting rate of Pachyphytum diangi. Background technique [0002] Dianzhonglou (parispolyphyllavar.yunnanensis) is a variant of Parispolyphyllavar.yunnanensis. As a precious medicinal plant, the steroidal compounds contained in its rhizomes have the effects of hemostasis, anti-inflammatory and analgesic. It is the "Yunnan Baiyao" ", "Gongxuening" and other famous Chinese patent medicines are one of the main raw materials. The reproduction methods of Chonglou Dianchi mainly include seed propagation and rhizome cutting propagation, but Chonglou Dianchi is a single-flowered single-fruit plant, and the number of seeds in the natural state is small, with an average of about 33 seeds per fruit. The seed yield cannot meet the needs of planting and production. In order to meet the actual needs of production, it is very important to improve the seed setting r...
