Embodiment 1

[0020] A kind of corn seed seedling raising method is characterized in that, comprises the steps:

[0021] (1) Seedbed preparation: In the greenhouse, use the nutrient soil composed of humus, coconut peat and perlite soil in a volume ratio of 2:3:1 to form a seedbed, and drench it with 1700 times thiophanate-methyl solution , standby;

[0022] (2) Seed germination: select plump corn seeds and soak in 0.06% potassium permanganate solution for 30 minutes, wash and set aside;

[0023] (3) Sowing: Open a shallow ditch with a depth of 4 cm on the seedbed, sow the corn seeds evenly in the shallow ditch with a row spacing of 6 cm and a seed spacing of 2.3 cm, and shovel fine soil from the ditch to cultivate in the hole The surrounding thickness is 4cm;

[0024] (4) Preparation of nutrient solution: add 0.4% KNO3, 0.6% NH4NO3, 0.4% Ca(NO3)2.4H2O to natural mineral water according to the weight percentage, add 0.1% solute amount every 10 days, and sprinkle it into the field three tim...

Abstract

The invention discloses a seedling cultivating method for corn seeds. The seedling cultivating method for the corn seeds is characterized by comprising the following steps of step 1, preparing a seedbed; step 2, accelerating germination of the corn seeds; step 3, seeding; step 4, preparing a nutrient solution; step 5, transplanting. According to the seedling cultivating method for the corn seeds, the operation of the planting method is convenient, the practicability is strong, the germination speed and the germination rate of the corn seeds are effectively improved through a way of combining the accelerating germination and the seedling cultivating, the seedling quality is improved, healthy and strong seedlings are cultivated, and the grain yield is improved.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a method for raising seedlings of corn seeds. Background technique [0002] Corn is the largest food crop in China. The total planting area of ​​corn is about 1249.35 square kilometers. Cantonese is called corn, and Hokkien is called fanmai. It is an annual grass herb, an important food crop and an important source of feed, and it is also the food crop with the highest total output in the world. [0003] Poaaceae plants are tall, with strong, straight stems, 3-5 meters high and 2-5 cm in diameter. The leaves are narrow and large, with wavy edges, alternate on both sides of the stem, the leaves are linear to linear-lanceolate, 40-60 cm long, 4-8 cm wide, apex acuminate, base round or slightly ear-shaped, surface dark Green, light green on the back, ciliated on both sides, wide midrib, white. Hermaphroditic, male flower inflorescences are terminal, and female ...
