Problems solved by technology

However, how to prevent and control plant diseases and insect pests in the process of corn growth is a problem that we are currently facing. The seedlings themselves have poor disease resistance, and the root system is severely damaged. On the basis of production and production, it is of great significance to improve the ability to prevent pests and diseases

Embodiment 1

[0016] A method for raising seedlings of disease-resistant corn, characterized in that it comprises the steps of:

[0017] (1) Seedling bed preparation: Use bentonite, humus soil and decomposed sheep manure sieved through a sieve with an aperture of 1.5mm to prepare a seedling substrate at a weight ratio of 5:3:2, using 50ml / m 2 The Smedi and 2% ferrous sulfate solution are evenly sprayed on the soil surface;

[0018] (2) Manufacture coated controlled-release fertilizer: take an organic fertilizer with a molar ratio of nitrogen, phosphorus, and potassium of 3:5:6, and apply it in the holes at a dosage of 25g per plate;

[0019] (3) Sowing: Soak the seedlings in 15mg / L naphthaleneacetic acid aqueous solution for 3 hours. After applying controlled-release fertilizer on the seedling tray, sow 2 seeds in 0.3 cm seed holes, spread 2 cm thick wheat straw on the seeds, and press 2 cm thick Fine soil;

[0020] (4) Watering and fertilization: After emergence, spray once every 5 days,...

Abstract

The invention discloses a seedling breeding method of disease-resistant corns. The seedling breeding method is characterized by comprising the following steps that firstly, a seedling growing bed is made; secondly, coated controlled-release fertilizer is manufactured; thirdly, sowing is conducted; fourthly, watering and fertilizer applying are conducted. Sterilization and nutrient supplement are taken into consideration in all links of seedling growing according to the conditions such as climate and irrigation, root system rooting can be controlled, seedlings can adapt to the field environment very quickly, the tuber pathogenic bacterium infecting opportunity is reduced, seedlings grow vigorously, the survival rate is remarkably increased, and the yield is considerable.

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 disease-resistant corn. Background technique [0002] In addition to edible corn, corn is also the main raw material for industrial alcohol and shochu. There are many ways to process grains: wet milling method is to soak the grains in dilute sulfurous acid solution for 40-60 hours; dry milling method is to use spray or steam to moisten the grains for a short time; fermentation method is to convert starch into sugar and add Yeast turns sugar into alcohol. Other parts of the plant are also quite versatile: corn stalks are used to make paper and wallboard; bracts are used as filler material and grass weaving; In addition to feed, it is also a good raw material for biogas digesters. [0003] The diseases during the growth of corn mainly include large and small spot, head smut, bacterial wilt, viral disease and stem rot. Prevent ...
