It takes more than 90 days from sowing to flowering. If seedlings are planted directly in open or protected areas, the growth of seedlings will take up half of the frost-free period, which will inevitably shorten the fruit harvest season and reduce the yield of peppers. In the period of frost, use facilities to raise seedlings in advance so that the peppers can be spent in the facilities from sowing to early flowering. Just after the end of the frost, colonize the open ground or take protective measures to cultivate the peppers in the frost-free season under the conditions of the facilities. This effectively extends the harvest time of pepper fruits and can significantly increase yield.
Cultivating seedlings of the right age is the basis for high yield and stable yield of chilli, which not only facilitates early maturation, but also promotes the development of peppers and reduces the incidence of pepper diseases.
The following measures are taken to cultivate pepper seedlings:
(1) If the seedling stage is properly managed, the seedlings will emerge faster after sowing. Generally, when the sowing depth is appropriate and the temperature and humidity of the seedbed are also suitable, the germinated seeds will start seedling emergence after 3 days sowing, and the seedlings can be established after 7 days; The speed is suitable, there is no leggy, nor is it because the growth rate is too slow to extend the nursery period or the formation of young seedlings.
(2) The normal seedlings showed thick, dark and glossy seedling stems, short internodes, and natural changes in stem height from top to bottom without any sharpness; the leaf size was moderate, the leaves were thick and dark, the leaves were intact, and disease-free. Injury to insects, good leaf extension, no wrinkling or curling; cotyledon intact, stretch natural, not curly; growing point full and full, bright heart color; pepper buds large and full, not deformed; roots developed, more lateral roots The root color is natural and does not change color.
(3) After sowing, germination and emergence are neat, no shortage of seedlings; pepper seedlings are well-growth, seedling height, leaf number, seedling stalk robustness, flower bud emergence, and quality are all relatively neat and well-ordered.
