Abstract

The invention discloses a method for transplanting corn in a zero-leaf stage. Seedlings are transplanted when corn coleoptiles come up but leaves do not come out yet, so that recovery growth of the seedlings is fast, growth is large, and cultivation of strong seedlings is facilitated.

Description

A kind of 0 leaf phase of corn method for transplanting

Technical field

A kind of 0 leaf phase of corn method for transplanting, belongs to Technique for Corn Cultivation field, more specifically says a kind of method of transplanting in the 0 leaf phase of corn.

Background technology

Corn is a kind of important cereal crops, and transplant planting is an ancillary technique measure in maize culture.Suitable seedling age phase transplant can make Seeding planting after lag phase short, recover growth fast, be conducive to corn and early send out fast longly at limited Seedling Stage, expand rapidly trophosome, for high yield is put up high yield shelf.But its suitable transplanting time never has definite conclusion, is necessary to be determined.

Summary of the invention

The object of the invention is for the problem that in current corn transplant planting, suitable Planting time be there is no clear and definite technical specification, a kind of method of corn 0 leaf phase transplanting is provided, be beneficial to cultivate strong sprout, improve output.

Technical scheme:

A kind of 0 leaf phase of corn method for transplanting comprises the following steps:

(1) the 0 leaf phase that is chosen in corn seedling transplants;

(2) transplanting method:

1. from seedling bed, by bud scale, just unearthed corn seedling has been grubbed out;

2. output in field planting district the shallow ridges that 2cm is dark;

3. in shallow ridges, water permeable;

4. seedling is swung in shallow ridges, push down root with dry ground piece;

5. with hack, shallow ridges is filled and led up;

6. next day and ground water to seedling for 3 days continuous two days, can survive.

Beneficial effect of the present invention: the 0 leaf phase of corn transplants, compared with transplanting, can make planting of seedling hinder minimum with other Leaf-Age-Period, slow seedling after cultivation is stagnant short for a long time, early sends out fast length after slow seedling, can maximally utilise the limited seedling growth stage, put up high yield shelf, for high yield lays the foundation.

Accompanying drawing explanation:

Fig. 1 is the impacts of different transplanting times on milpa fresh weight and dry weight;

Specific embodiment:

We have arranged the test of the suitable setting date of corn in the plantation Technology Park of Anhui Science and Technology College spring in 2012.

Test is processed: transplant at 0 leaf (be that bud scale is unearthed, blade is not current), 1 leaf, 2 leaves, 3 leaves and 5 Leaf-Age-Periods of 4 leaves of corn seedling respectively, 30 strains are transplanted in every processing, repeat for 3 times.Within after field planting 20 days, measure fresh weight and the dry weight of plant.

Transplanting method:

1. at different Leaf-Age-Periods, seedling is grubbed out out from seedbed;

2. output in field planting district the shallow ridges that 2cm is dark;

3. in shallow ridges, water permeable;

4. seedling is swung in shallow ridges, push down root with dry ground piece;

5. with hack, shallow ridges is filled and led up;

6. next day and ground water to seedling for 3 days continuous two days,

Result of the test: Fig. 1 shows, the processing that the 0 leaf phase of corn transplants, and the fresh weight of plant and dry weight, all higher than the processing of other Leaf-Age-Period, illustrate that the effect of corn 0 leaf phase transplanting is best.

Claims (1)

1. 0 leaf phase of a corn method for transplanting, is characterized in that, it comprises the following steps:

(1) the 0 leaf phase that is chosen in corn seedling transplants;

(2) transplanting method:

1. from seedling bed, by bud scale, just unearthed corn seedling has been grubbed out;

2. output in field planting district the shallow ridges that 2cm is dark;

3. in shallow ridges, water permeable;

4. seedling is swung in shallow ridges, push down root with dry ground piece;

5. with hack, shallow ridges is filled and led up;

6. next day and ground water to seedling for 3 days continuous two days, can survive.
