Early ripening maize high-yield cultivation technology

Abstract

The invention provides an early ripening maize high-yield cultivation technology, belongs to the field of agriculture, and especially relates to a maize cultivation technology. The invention provides the early ripening maize high-yield cultivation technology which is fast in grouting and full in particles. The early ripening maize high-yield cultivation technology is characterized by comprising the following steps: 1, processing seeds and selecting seeds, pelleting seeds, using a seed coating to coat, to prevent and control pest and disease damages; 2, sowing and conserving seedlings: (1) ensuring soil moisture and sowing in proper moisture in soil, appropriately sowing early, on 5-10 cm land, when ground temperature being constant at 8 DEG C, sowing, to prevent sowing too late; 3, applying fertilizer and irrigating, according to target yield and foil fertility, determining fertilizer and water safeguard measures, to strictly guard against drought, especially paying attention to moisture supply in a critical period; 4, controlling pests and diseases later, in a belltop stage, using 10 ml chlorantraniliprole.thiamethoxam, 15 ml Ainong, and 30 kg water in each mu, spraying on stem leaves, to prevent European corn borers, oriental armyworms, aphids, and leaf spot diseases, rust disease, and gall smut, etc.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a corn cultivation technique. Background technique [0002] Early-maturing corn has a growth period of 111 days and requires an effective accumulated temperature of 2120°C. It is known for its early maturity, dense planting, and high yield. In March 2005, it passed the approval and promotion of Heilongjiang Crop Variety Approval Committee. The seedlings have strong soil arching ability, fast seedling emergence, low temperature resistance, and dark green leaves. The plant type is convergent, the internodes on the ears are long, the group is well ventilated and light-transmitting, the aerial roots are well developed, and the stalks have strong lodging resistance, so they are suitable for dense planting. The height of the adult plant is 237cm, the ear height is 93cm, the number of leaves is 18 pieces, the ear is nearly cylindrical, the ear length is 19.5cm, the ear diameter ...
