Management of summer tulips
The flowering period of tulips is from March to May every year. After the tulip blossoms, the underground part of the new bulb develops rapidly, and the mother bulb disappears as a seed bulb. So the tulips should immediately cut off the pedicels and plant the leafy bulbs in the pot (or on the ground). Basic fertilizer should be added first, preferably bean cake crumbs and bone powder to promote the growth of the split bulbs. the new bulbs develop from the lateral buds in the axils of the mother's fleshy scale leaves. When the terminal buds of the mother bulbs form flower buds, the lateral buds germinate.
During the period of promoting the germination of lateral buds, thin fertilizer should be applied two or three times, and usually it should be watered to prevent drying.
When the tulips enter the semi-dormant period in summer, the bulbs should be dug out of the basin, dried and stored. According to the growth law of apical dominance, the development of the first lateral bud below the apical flower bud is the most robust and can become a good flower bulb, and the order of the following lateral buds is weakened. Wait until September to October and then re-pot the good flowering bulbs and apply base fertilizer. It can be planted in the open field in winter, and the pot can be placed in a warm place facing the sun outside. the pot soil should be dry and avoid dampness. in this way, after the Beginning of Spring next year, it will grow new leaves from the soil, apply thin fertilizer twice, and bloom again in March or April.

Does the application of chlorosulfuron in wheat field affect cotton?
Chlorosulfuron is a sulfonylurea herbicide with high herbicidal activity. It is mainly used to control annual monocotyledon and dicotyledonous weeds in wheat and flax fields. At present, it is only used in wheat fields in the Yangtze River valley. It is not easy to decompose in soil, and the residual period is as long as 6 months. Crops such as cotton, peanuts, soybeans and vegetables are sensitive to the drug. Different degrees of drug damage will occur when chlorosulfuron is applied in wheat fields and sensitive crops such as cotton are planted in the following crops. Wheat fields with chlorosulfuron had better not transplant cotton, but can plant other crops with strong drug resistance.

Why do my tulips have short stems and small flowers?
The quality of home-cultivated tulips is not as good as those sold in the flower market, usually showing short stems and small flowers. the main reasons are as follows: first, the varieties with different genetic basis have great differences in stem length and flower diameter. Second, the varieties were degraded by continuous cultivation for 2 to 3 years, and there were great differences between the cultivation environment and the ecological conditions of the origin of tulips, especially the high temperature in summer, unreasonable fertilization during the growing period and other factors, which were easy to cause the degradation of seed bulbs. General commercial seed bulbs can only be planted for 1 to 2 years without taking corresponding rejuvenation measures.
