Abstract
The invention discloses a double-row spaced planting method of corn inter-planting in corn field; the number of total rows of double-row spaced planting is more than the number of total rows of single-row planting by one time; the seedling is positioned in double rows by adopting an alternating method and the number of the left seedling is increased by 10 percent to 20 percent compared with the equal row spacing type. The double-row spaced planting method of the invention not only can improve the corn yield but also fully utilizes the illumination resource and utilizes the land resource reasonably.
Description
Technical field
The present invention relates to agricultural planting technique.
Background technology
For a long time, the field planting specification of China's field corn generally be big or small line or etc. the line-spacing formula.The size line mainly is that the cornfield interplanting corn adopts, and is prevailed the 1970s and 1980s in last century, for promoting the corn per unit area yield to play certain effect by low yield to middle product transition.But this method is on the low side to land utilization rate, and wheat influences output too greatly because of the furrow back ofs the body, and corn also is difficult to increase density because of line-spacing is excessive, becomes the barrier factors that product in the corn of cornfield interplanting uprises product.
Along with the raising of the level of the productive forces, at present more the cornfield interplanting corn adopts and waits line-spacing to stay the interplanting row, and the corn average row is apart from progressively narrowing down to 60-70cm by 90-100cm, for corn increases density and improves regularity and created condition.The average density of reserved seedlings of present field corn, open and flat large spike is 3000-3500 strain/mu, fringe type 4500-5500 strain/mu in the compactness, compact large spike is 3500-4500 strain/mu.The expert generally believes, the maximum leaf area index of current open and flat large spike corn is 4.0, the maximum leaf area index of fringe type corn is 6.0 in the compactness, to have influence on single plant yield as the planting density that increases every row again, per mu yield does not only improve, even can also the underproduction, analyzing underproduction reason is overstocked influence growth between strain.
At present, also there is the excessive defective of line space in the cornfield interplanting corn, and the excessive printing opacity that occurs of line space can not make full use of the illumination resource and rationally utilize land resources.
Summary of the invention
The objective of the invention is the defective of staying seedling field planting specification at above-mentioned cornfield interplanting corn, propose a kind of duplicate rows thin planting method,, improve group structure better by reasonable increase density, effectively improve population photosynthesis effect and utility rate of luminous energy, give full play to the soil fertility effect and reach the purpose of volume increase again.
Duplicate rows thin planting method of the present invention is, changes the single file plantation of existing corn planting specification into the duplicate rows plantation, and promptly total line number doubles, and adopts the alternating method final singling between duplicate rows, stays seedling strain number to increase 10-20% than the existing line-spacing formula that waits.
Good effect of the present invention is:
1, the rare value method of corn duplicate rows of the present invention, light and heat energy and soil fertility resource theory have been followed, science is coordinated the field layout of individual plant, makes great efforts to optimize group structure, has increased whole strain number by increasing line number, but the distance between strain and the strain strengthens, gather around and do not squeeze, so promptly reduced mutual shading and light leak in the ranks, improved space utilization efficient again, reach the optimum leaf area index, improved population photosynthesis effect and utility rate of luminous energy.Plane distribution is loose even between the underground root system simultaneously, and longitudinal growth is in picturesque disorder, and it is idle to have reduced local nutrient contention and part soil fertility, and monomer is grown healthy and strong, and land utilization efficiency is higher.This group structure, the growing environment advantage of corn individual strengthens, and vying each other between the individuality weakens, and finally having reached increases density, improves regularity and the purpose increased production.Produce corn 100g by every strain and calculate, every mu is increased production more than the 50kg at least.
2. corn duplicate rows thin planting method had both adapted to open and flat blade profile corn, more adapt to compact leaf corn; Both suitable cornfield interplanting, sowing in the field preferably (having the expert to point out, live after the more suitable wheat harvest of current summer corn).Neither influence wheat yield during cornfield interplanting and also increased corn yield again.
Description of drawings
Fig. 1 is a corn duplicate rows thin planting method schematic diagram of the present invention.
Specific implementation method
As shown in Figure 1, corn duplicate rows thin planting method of the present invention is: spacing a=15cm in the duplicate rows; The spacing b=65cm of duplicate rows and duplicate rows, the laggard seedling in the ranks of emerging stays a little less than strong the going, and keeping open and flat large spike spacing in the rows c=is 40cm, and fringe type spacing in the rows is c=30cm in the compactness, and compact large spike spacing in the rows is c=35cm, adopts the alternating method final singling between duplicate rows.
Above-mentioned spacing in the rows is the average spacing in the rows of every row.
Claims (1)
1, a kind of duplicate rows thin planting method of cornfield interplanting corn is characterized in that, the total line number of its plantation is planted total line number than single file and doubled, and adopts the alternating method final singling between duplicate rows, stays seedling strain number ratio to wait the line-spacing formula to increase 10-20%.
