Chongqing: plastic foam disc corn seedling effect is good
Shizhu County fishpond Zhen Tuan Jie Cun planting large et al beginning in 2014, reference to the method of tobacco seedling seedling of corn, and good results have been achieved, suggested the country next year experiment and demonstration. To use plastic foam disc fertility of maize seedlings advantage: one is Gen Jian, stem diameter, leaf width, is conducive to reviving after transplanting seedlings; the second is seedling in a short time in the greenhouse and in the suitable sowing date of sowing and seedling, 10-15 days can cultivate a group of maize seedling; three is less nutritious soil, reduced the seedling transportation and employment, and improve the efficiency of the maize transplanting. In applying base fertilizer, finishing well cultivated conditions, a labor can transplanting 10 acres of corn.On the other hand,polyethylene foam recycling and EPS recycling is necessary.
The specifications of the foam disk are: 6 cm high, 34 cm wide, 66 cm long. Each disc 10 x 20 hole, hole bottom with drainage holes, each nursery holes in sowing 2 grains of corn seed, each disc can brood nest 200, 400 strains of maize seedling, per acre to 7.5-8 sheets of foam seedlings.
Seedling raising methods: first, the establishment of fat basin. The size of the fertilizer pool according to the size of the seedling, in the case of the sowing period, can be implemented by stages, each pond can be bred 2-3 batch of corn seedlings, pool depth should be 20 cm or more. Before seeding, in pond irrigation depth 6-7 cm, per square meter fat pool application content 45% (n, P, K 15% each) compound fertilizer 0.3 kg, before the second batch seedlings and compound fertilizer 0.15-0.18 kg. Two is the establishment of greenhouse. In the fat around the fountain with a steel frame or bamboo frame to build a greenhouse, greenhouse height is 1.8-2 meters. Three is the sowing plate. Humus soil to fill the seedling planting hole and jitter, promote humus compaction, followed by sowing, each hole sowing 2 corn seed, after sowing and then a little humus to cover the seed. After seeding the foam seedling plate placed in the fat basin, the water level line between the foam height 2/1 to 2/3. When the corn seedling reaches 3 leaves, it can remove the seedling plate from the fertilizer sink, remove the corn seedling and transplant it to the field transplanting..
