Abstract

The invention discloses a sorghum sudanense 0 leaf stage transplanting method. According to the sorghum sudanense 0 leaf stage transplanting method, transplanting is carried out on seedlings before coleoptiles of sorghum sudanense come up and leaves do not emerge; the recovery growth of the seedlings is rapid and the growth amount is great; strong seedlings are easily cultivated.

Description

A kind of 0 leaf phase of Sudan grass method for transplanting

Technical field

A kind of 0 leaf phase of Sudan grass method for transplanting, belongs to Sudan grass culture technique field, says more specifically a kind of method of transplanting in the 0 leaf phase of Sudan grass.

Background technology

Sudan grass is a kind of important forage crop on livestock breeding is produced, and transplant planting is an ancillary technique measure in Sudan grass cultivation.Suitable seedling age phase transplant can make Seeding planting after lag phase short, recover growth fast, be conducive to Sudan grass and early send out fast longly at limited Seedling Stage, expand rapidly trophosome, for the high yield of cursive script 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 Sudan grass transplant planting, suitable Planting time be there is no clear and definite technical specification, provides the method for 0 leaf phase of Sudan grass a kind of, is beneficial to cultivate strong sprout, improves output.

Technical scheme:

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

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

(2) transplanting method:

1. from seedling bed, by bud scale, just unearthed Sudan grass 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 Sudan grass transplants, compared with transplanting with other Leaf-Age-Period, can make planting of seedling hinder minimum, slow seedling after cultivation is stagnant short for a long time, after slow seedling, early send out fast long, can maximally utilise the limited seedling growth stage, put up high yield shelf, for the high yield of cursive script lays the foundation.

Accompanying drawing explanation:

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

specific embodiment:

We have arranged the test of the suitable setting date of Sudan grass in the plantation Technology Park of Anhui Science and Technology College spring in 2012.Sudan. grass Varieties is Sa.

Test is processed: carry out Transplanting Test at 0 leaf (be that bud scale is unearthed, blade is not current), 1 leaf, 2 leaves, 3 leaves, 4 leaves and 6 Leaf-Age-Periods of 5 leaves of Sudan grass 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 Sudan grass 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 Sudan grass 0 leaf phase transplanting is best.

Claims (1)

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

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

(2) transplanting method:

1. from seedling bed, by bud scale, just unearthed Sudan grass 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.
