Abstract

The invention discloses a seedling colonization method for promoting rice tillering. The seedling colonization method comprises tray-soilless seedling cultivation in a three-joint mode, strong seedling cultivation, colonization in good time and of the right age, and wide and narrow row spacing stagger positioning. The seedling colonization method has the advantages that root system connection is formed through sinking of jointed parts of three adjacent holes, microspur tray-soilless seedlings are cultivated, and rice tillering is promoted through rice plant reasonable scattering and tray-soiled growing; three-joint pot seedlings are distributed in a triangular mode in width distance, growing space is effectively utilized, and tillering and strong growing are facilitated; a field is of a wide and narrow row spacing structure on the whole, ventilation performance is improved, generation of large panicles on the basis of enough panicles is facilitated, and production of rice in the super high yield is achieved.

Description

Promote the field planting method of growing seedlings that rice tillering is early sent out

Technical field

The present invention relates to a kind of field planting method of growing seedlings that promotes that rice tillering is early sent out.

Background technology

Existing seedling cultivation of rice field planting method, the growing space is little, is unfavorable for the multiple stalwartness growth of tillering and tillering.Need further to be improved.

Summary of the invention

The object of the present invention is to provide a kind of method easy, be beneficial to the field planting method of growing seedlings that multiple promotion rice tillering of tillering and tillering healthy and strong growth is early sent out.

Technical solution of the present invention is:

A kind of field planting method of growing seedlings that promotes that rice tillering is early sent out, it is characterized in that: the point disk seedling growing that 1. adopts the triplet formula: the hole is the alms bowl bodily form, 1 centimetre of diameter, dark 2 centimetres of hole at the bottom of 2 centimetres of the cave face diameters in each hole, the cave, the permeable small sircle hole of using that 0.4 centimetre of diameter is arranged at the bottom of the cave, three adjacent hole distributions triangular in shape, company's connection part in three adjacent holes is sunk 0.6～0.8 centimetre, the part of sinking is impelled the root system string knot in its adjacent three holes by the distribution soil of growing seedlings, during field planting naturally formation be the tri-coupling type seedling in earthen bowl of little triangle; 2. cultivate strong sprout: adopt the seedling of drought bed, put seedling cave dish in the seedbed, after the seedling dish is put, in fertile fine earth filling dish hole, be filled to 2/3 high place of hole earlier, every bunch planting kind is through 1～2 of the bud kind of presoaking and germinating, the remainder of after planting recharging 1/3 nutrition soil or fine earth highly, sweep clean card earth, spill sufficient moisture, cultivate strong sprout.3. in good time of the right age field planting: rice shoot 3～4 leaves field planting land for growing field crops during the phase, fine weather is field planting after 3 o'clock in the afternoon, is no more than 2/3 hour from dish to the field planting land for growing field crops; 4. the width line misregistration is located: land for growing field crops tep reel water planting, 35～40 centimetres of the wide every trade distances of planting, 20～25 centimetres of narrow rows, 15～18 centimetres of the spacings of the interior triplet pot seedling of every row, pot seedling is alternating expression to be arranged, and constitutes between the seedling strain field that is 15～25 centimetres of width triangular shapes between 2～3 centimetres of microspur triangular forms, triplet pot seedling and distributes.

The present invention one is sunk by company's connection part of three adjacent holes (distribution triangular in shape), forms root system string knot, cultivates the triplet cave dish seedling of microspur, rationally disperses and the planting of cave dribbling soil by the rice strain, promotes rice tillering early to give birth to early and sends out; The 2nd, be width (15～25 centimetres) triangular shapes (between narrow row) between the triplet pot seedling and distribute, effectively utilized the growing space, be conducive to the multiple stalwartness growth of tillering and tillering; The 3rd, on the whole the capable structure of width on the field improves the ventilative performance of ventilation, is conducive to realize big fringe on the basis of sufficient fringe, and the superelevation that realizes paddy rice produces produces.
