水稻育苗墊育苗試驗

李文輝

摘  要

本試驗係利用紙漿育苗墊做為水稻育苗之材料,於民國66年期間在嘉義分場所進行之一系列有關水稻育苗試驗,全部試驗包括三項小試驗。試驗一為育苗墊育苗之肥料量與施肥法試驗,試驗二為不同育苗材料育苗比較試驗,試驗三為不同重量育苗墊育苗比較試驗,茲將試驗結果摘錄如下:

1.育苗墊育苗施肥以作基肥施用於箱底報紙上為宜,肥料量每箱以硫酸錏8公克,過磷酸鈣8公克,氯化鉀4公克為最佳,如肥料過量易發生肥傷,若將肥料混合土壤覆蓋於種子上亦容易發生肥害。

2.育苗墊保水力較土壤強,故第一期作之防寒害,及第二期作之防缺水,育苗墊均較土壤為佳,但秧苗初期生長土壤者較育苗墊者快且整齊。

3.育苗墊秧苗二期作在播種後30天,根部尚很健旺,而土壤育苗者25天以後,根部即有老化之現象。

4.稻藁,未經紛碎之稻穀,木屑等均不太適宜做為機械插秧用之育苗材料。

5.育苗墊重量以240公克至280公克為宜,太輕太重均不佳。

6.育苗墊育成之秧苗在插秧時,根部需稍為沾觸田水,使秧片在插秧時易于滑落,減少缺株,並可使每欉苗數均一。

7.育苗墊可代替土壤來育苗,但成本高,不太經濟。


The research on the nursing of rice seedling in the paper-cushion bed

W. H. Lee

Summary

        The collection of bed-soil is getting more difficult when the rice transplanter becomes more popular.  A new solution to this problem is necessary, so we made an attempt to find out some new materials which could be used to substitute the soil for raising seedling.  One kind of paper cushions made of paper tissues was tested in these experiments.

1. 8-8-4 gram/box of N:P:K fertilizers should be uniformly spread on the newspaper which was laid on the bottom of the box.  Since fertilizer would cause damage on the rice seedling if it were applied on the top soil which was used to cover the seeds.

2. Since the water keeping ability of the paper-cushion was stronger than that of the soil, therefore, rice seedlings growing in the paper-cushion were more resistant to freezing and water shortage.

3. The senescence in the paper-cushion rice seedlings was appeared later than that in the soil seedlings.

4. The data showed that straws, un-milled hulls, and saw-dust were not good for nursing purpose.

5. The optimum weight of paper-cushion for nursing was from 240 gram to 280 gram per box

The data above indicated that paper-cushion can be used as a new material to substitute the soil for rice nursing, but it is too expensive to be adopted.
