The invention discloses a soilless
straw matrix of rice dry-raising
water pipe and a
seedling culture method. The method includes the following steps that a
seedbed and the soilless
straw matrix are manufactured; by means of the deep-
ditch and high-box mode, water and
fertilizer are controlled and growth of rice seedlings is regulated through a
seedling box, wherein the
seedling age of seedlings transplanted by machines is prolonged by 5-10 days, and the
crop rotation contradiction of rice
transplantation is effectively relieved; meanwhile, the soilless
straw matrix matched with seedling culture of the method is formed by smashing oilseed rape straw serving as the main
raw material and adding
disinfectant, a water-retaining agent, modifier, an acid regulating agent,
fertilizer and the like; a plastic tray with the specification of 58.8 cm*28 cm*2 cm is used for seedling culture; seedlings grow in the disinfected and appropriate acid condition; growth of seedlings is regulated through the water control and
fertilizer control measures in the seedling culture process, and therefore the aims of being strong in seedling, large in
root number, thick in rod and green in leaf are achieved.
Straw is directly used as the soilless straw matrix after being smashed, the production processes of soil taking, soil screening and the like are reduced, and the labor intensity of rice farmers is lowered.
