Two-line synchronous corn-culturing method with wide-narrow hill spacings at ridge sides

A cultivation method and technology of wide and narrow holes are applied in the field of simultaneous cultivation of double rows of wide and narrow holes on the side of corn ridges, which can solve the problems of corn not being able to achieve permeability, unable to use large ridges for planting, poor quality of corn, etc. The effect of lodging performance, improving water retention and resistance to spring drought, and increasing planting density

Problems solved by technology

[0002] At present, due to the high development of agricultural mechanization in Heilongjiang Province, the planting method of corn has changed in Heilongjiang Province. Most farm reclamation areas in our province have fully promoted the double-row planting of corn in large ridges. This cultivation technology solves the problem of large-scale planting. The ventilation and light transmission between rows on one side of corn has played a certain role in increasing the yield of corn. However, for many existing small ridges, the method of planting on large ridges cannot be used, so the corn planted on small ridges still cannot achieve effective results. Permeability, the growth of corn in an airtight environment seriously affects its yield, and the quality of corn is poor and easy to lodging

specific Embodiment approach 1

[0024] Specific implementation mode one: the corn ridge side two-row wide and narrow hole spacing synchronous cultivation method of the present embodiment is carried out according to the following steps:

[0025] 1. Ridging for site preparation, the distance between ridges is 65-70cm;

[0026] 2. When sowing, take two ridges as a unit, and sow corn seeds in the way of double rows of wide and narrow holes and double grains inside the two ridges. The cross-section of the ridges can be seen from the appearance figure 1 , the highest part of the top is called the ridge platform, the lowest part of the bottom is called the ridge bottom, and the side between the ridge platform and the ridge bottom is called the ridge side, also known as the ridge side. A ridge has a ridge platform, two ridge sides and two ridge bottoms. The "double row inside two ridges" refers to planting a row of seeds on the inner sides of two ridges of a unit, such as figure 2 shown. "Wide and narrow holes a...

specific Embodiment approach 2

[0039] Specific implementation mode two: figure 1 and 2 As shown, the double-row wide and narrow hole spacing synchronous cultivation method on the corn ridge side of the present embodiment is carried out according to the following steps:

[0040] 1. Land preparation and ridge, requirements: the original ridge and stubble removal and rotary tillage.

[0041] 2. Seed selection, corn variety: Duyu No. 1.

[0042] 3. Sowing, the best sowing period in Harbin is from April 20th to May 5th.

[0043] 1. The planting mode, the two ridges form a combination, and the inner side of the two ridges is sown with double rows of wide and narrow holes.

[0044] 2. 4000 seedlings per mu, 2000 holes per mu, 2 seeds per hole, 4000 seeds, ridge width 66.7cm, ridge side double row width 40cm, wide row spacing 93cm, double row synchronization: wide hole spacing 66cm, The distance between the narrow holes is 33cm (such as image 3 shown).

[0045] 4. When sowing corn in two rows on the original...

Abstract

The invention discloses a two-line synchronous corn-culturing method with wide-narrow hill spacings at ridge sides, and relates to a ventilation corn culturing method with high light-efficiency utilization. The culturing method comprises the main steps of: ridging, soil scraping at a ridge surface, furrowing, sowing, earth backing, fertilization and regulation. The specific requirements are as follows: the land is prepared and ridged, and the ridge spacing is 65-70cm; and the two ridges form a combined body, 1800-2000 holes are sowed in each acre with two seeds for each hole; and the line spacing of the narrow lines in sowing is 40-50cm, the line spacing of the wide lines in sowing is 80-95cm, the distance between the two-line synchronous wide-line holes is 70-66cm, and the distance between the two-line synchronous narrow-line holes is 35-33cm. The two-line synchronous corn-culturing method with the wide-narrow hill spacings at the ridge sides, disclosed by the invention, has the advantages that the blank for two-line corn planting with large-ridge soil preparation is filled, and the two-line corn culture at the ridge sides can be used to achieve the same benefit as that of the two-line core culture at large ridges. Superior to the single-side ventilation of two-line corns at the large ridges, the two-line synchronous corn-culturing method can be used to realize two ventilation side surfaces for each corn plant, and the cross ventilation of large-area corns, so that the light-efficiency utilization for the corns is increased.
