Appropriate late-seedling corn is one of the main technical measures suitable for the cultivation of northern spring maize, increasing the number of harvested panicles, and increasing the yield, which has been verified through large-scale production practice.
Appropriate late seedlings of corn should be seedlings in the period of 3-4 true leaves of the corn. The seedlings should be seeded on 6-7 true leaves and physiological secondary differentiation phases based on two strong seedlings per hole. The main benefits are: to reduce the damage to corn seedlings caused by maize rough dwarf disease, corn borer and seedling pests, and increase the number of nursery plants per unit area by more than 15%.
Reduce the percentage of weak seedlings, false seedlings, diseased seedlings, self-inoculated seedlings and strong seedlings of maize, increase the number of grain spikes per hectare and 100-grain weight by more than 10%, and increase corn yield. Every 667 square meters save corn seedlings for the prevention and treatment of diseases and insecticides and seedlings for seed replanting costs 15 yuan -20 yuan.
Hydroponics is a subset of hydroculture, the method of growing plants without soil, using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the mineral solution, or the roots may be supported by an inert medium, such as perlite or gravel. The nutrients in hydroponics can come from an array of different sources; these can include but are not limited to waste from fish waste, duck manure, or normal nutrients.
