When does spring peanut control prosperous medicine?

Spring peanut is the most suitable for controlling the growth when the needle is dropped or when the plant height is 30-40 cm. Paclobutrazol, uniconazole, mepiramine, dwarf, butyrylhydrazide, pyridinol and other agents can be selected according to the need, and generally used for 2-3 times. In addition, the prosperity can be controlled manually by stepping on the seedlings.

When will spring peanuts be sown?

The sowing time of spring peanuts is different in different regions:

1. The suitable sowing time for spring and autumn double cropping peanut areas in South China is from February to mid-March, and the suitable sowing date for spring and summer peanut intercropping areas in the Yangtze River Basin is from March to late April.

two。 The suitable sowing time for large peanut areas and peanut producing areas in northern China is from late April to early May.

3. The temperature of peanut germination: the pearl bean type and multi-grain type can germinate above 12 ℃, while the common type and dragon type can germinate only after 15 ℃, and the sowing time is a little later.

During the growth period of spring peanut, if the soil fertility is high, the temperature is high and the humidity is high, the phenomenon of overgrowth, vigorous growth and premature senescence of peanut is easy to occur, which will reduce the number of flowering and pod of peanut and lead to the decrease of peanut yield. In order to ensure the high and stable yield of peanuts, we need to control the growth of peanuts in time so as to promote the transformation of peanuts from vegetative growth to reproductive growth as soon as possible.
