Problems solved by technology

[0002] The propagation of neem is mainly based on seed sowing, but the seeds of neem are fleshy fruits, the seed coat structure is hard, dense, and impermeable, the germination rate of untreated seeds is extremely low, and the soil requirements are very high, so the survival rate of direct sowing is very high. Low, need about 40~50 days to begin to germinate; Although there is the method for utilizing seedling raising substrate to raise seedlings in the prior art, its emergence rate and transplanting survival rate are not ideal, and blight disease is very serious during seedling raising in addition; Therefore, the invention A method for sowing and raising seedlings of neem that can effectively solve the above problems has great significance

Abstract

The invention belongs to the technical field of seedling cultivation and particularly relates to a sowing and seedling method for melia azedarach. The method includes the specific steps that firstly, selection and treatment of seeds are conducted; and secondly, sowing and management after sowing are conducted, wherein when seedlings grow to be 6 cm to 7 cm in length, one seedling growing to be robust is reserved in each hole, the treatment of filling gaps with seedlings is conducted in seedling culturing holes without the emergence of seedlings, then a nutrient solution begins to be sprayed, and spraying is conducted every other 14 days to 16 days till transplanting is conducted. According to the sowing and seedling method, the seedling emergence time of the melia azedarach is shortened to 8.1 days to 8.4 days, the seedling emergence rate reaches 96% to 96.7%, the damping off disease rate is reduced to 2.1% to 2.4%, the transplanting survival rate reaches 98.2% to 98.5%, and the seedling culturing quantity and the seedling culturing quality are effectively improved.
