Many flower friends have big rock Tung at home, but sometimes the bulbs rot when they are raised. At this time, the flower friends are confused.... What should we do now? Well, let the omniscient editor of plant house tell you what to do~
How to deal with the rotten bolus? Before dealing with the rotten bolus, you must confirm that the seed ball is hard, not soft. If it is soft, throw it directly. (warm tips: the following methods are also applicable to big rock, medium rock, Miyan and other bulbs. I hope they can be helpful to Huayou ~)
The first step is to dig up the seed ball, wash it and tear off the rotten roots (be careful not to brush with a brush, so as not to brush off the skin and growth points).
The second step is to cut off the black (rotten) place with a sharp knife until the white meat is seen, so as to prevent the whole ball from being infected and blackened.
The third step is to put the cleaned Corydalis Corydalis in the sun for about half to an hour (if the ball is too small, it is easy to dry and dehydrate), dry the wound and sterilize. Then apply carbendazim.
The fourth step is to prepare the water moss (of course, other clean sterile plain soil (vermiculite, perlite, river sand, etc.) can be used, but the water moss can be twisted dry, easy to grasp the humidity, fluffy and breathable) to water, twisted dry to no dripping water.
Then cover half of the bulb with water and try not to cover the wound. Use a transparent container to close it. It's better to ask the container not to appear water drops, because there is a wound. It's too wet and easy to rot. If there is no wound in the ball germination, you can wet point, see the water is good.
The fifth step is to wait about a week or two for the seeds to germinate again. After germination, pull the water moss as clean as possible, and try not to break the root. If you can't get rid of it, take a small amount of water moss, bury half to half of the bulb in the moist soil, and plant it back.

Maintenance methods of Jatropha speciosa
1. Temperature. According to the ecological habits of Jatropha speciosa. The suitable temperature for growth and flowering is 20-25 ℃. When the temperature is higher than 30 ℃, the plants will wither and turn yellow. It can be cooled by shading, ground watering and other methods to avoid strong direct light. Air conditioning can be used to adjust the temperature in family maintenance. When the temperature drops to 10 ℃ in winter, it will gradually enter the dormancy period. At this time, the tubers should be stored in sand or with basin in a ventilated and dry room with the temperature of 10-12 ℃. If the humidity is high and the temperature is low, the tubers are easy to rot.
2. Watering. During the growing period, the air humidity should be increased to make the leaves green and grow luxuriantly; the basin soil should be wet, if the water is too dry, the leaves will turn yellow; if the basin soil is too wet, it will cause excessive growth, which will lead to non opening, softening and bud withering. Because of its sensitivity to minerals and other impurities in water, the tap water for city use must be stored for one day before watering.
3. Fertilization. In order to master the principle of applying thin fertilizer frequently and fertilizing according to the growth trend, the cake fertilizer liquid with thin fermentation should be applied once every 10-15 days and mixed with other fertilizers. Nitrogen fertilizer was added at seedling stage and phosphorus fertilizer was added at flower bud differentiation stage. Fertilization is not allowed during hibernation. Do not contaminate flowers and leaves in fertilization, otherwise it is easy to cause leaf rot.
4. Pest control.
a. The main way to control the seedling Damping off disease is to strictly disinfect the culture soil and avoid excessive moisture or water accumulation in the basin soil.
b. For Botrytis cinerea which is harmful to leaves, stems and buds, spray 800 times 50% carbendazim diluent.
c. Inchworm is the main pest that damages leaves and buds. In family maintenance, it is better to catch it manually or spray jingyeling 1000 times in the morning and evening.
