Pollination of stone flowers
Parental selection of stone flower
For pollination, we should try to choose the close relative of the variety as the parent, and almost all the stone flowers with more than 5 years are good parents. At the same time, we should choose the side buds on two plants of the same variety p>
Pollination of stone flowers
The full flowering period of stone flower is very long. The best pollination period is the third to fifth day, and the best pollination period is around 4 p.m. every day. Pollination can be done by dipping pollen with a cotton swab and smearing it on the stigma of the female parent. If you want to cross, remove all stamens of the female parent on the first day of flowering, and then use ophthalmic forceps to clamp the stamens or anthers of the male parent and apply them to the stigma of the female parent p>
The stigma of the female parent was covered with pollen and turned yellow. The flower began to wither the next day, which proved that pollination was successful p>
Picking and sowing of raw stone flowers
Seed selection of raw stone flower
The fruit of the stone flower ripens in spring and can be harvested when it becomes dry p>
The harvested fruit should be cut from the base of the handle and dried in a dark and ventilated place. Don't rush to remove the fruit to get the seed, but put it into a sulfuric acid paper bag for preservation to promote the post ripening of the seed. It can be sown that autumn p>
Sowing of raw stone flower
The sowing choice is in the middle and late September of autumn, preferably dense sowing. Different varieties are sown separately in close quantity, and do not mix sowing p>
When sowing, a hard paper can be used to make a paper slot. Put the seeds in the paper slot and use tweezers to button the back of the paper slot. The seeds will be slowly and evenly dispersed to the surface of the basin soil along the slot. After sowing, cover with transparent glass plate to moisturize. Gradually remove the glass plate after one week, pad one corner of the glass plate first, and then pad another corner after one week. It can be completely removed in a month p>
Seedling management of stone flower
The glass plate should be removed gradually in the seedling stage of raw stone flower to maintain sufficient and soft light p>
Secondly, a variety of fungicides are used alternately, and some can be added each time. To ensure a high seedling rate p>
