落花生機械化栽培行型試驗

毛賢宗 徐進生

摘  要

本試驗按機械橫寬約略大小,分別設計四個試驗,為適應機械在田間操作,留有曳引機行道,便利機械行駛。每個均予三種行型設計,並以現行行株距(30cm×10cm,不留機械行道)為對照。結果,無論春,秋作,每個試驗各種行型處理的分枝數,單株莢果數,莢果重及子實產量的平均數量均較對照區減少,但亦偶有例外,各種行型與對照區相較剝實率(%)春作減少,秋作則互有增減。反之株高則較對照處理增加。

行道數與種植區數(兩行道間)的比較為(n+1):n,本試驗一小區內的(n+1):n=5:4或4:3。但如大面積栽培時,n→∞則(n+1):n≒1:1。設若面積為(10公頃100M×1000M),按(n+1):n≒1:1,計算子實產量時。則61年秋作(臺南)B-170cm的a種行型(每小區12行,株距7.0cm),C-180cm的b種行型(每小區12行株距6.5cm)。62年春作(臺南)C-180cm的a種行型(每小區12行,株距6.5cm)。62年秋作(臺南),A-160cm的a種行型(每小區種12行,株距7.5cm),b種行型(每小區9行,株距5.5cm),c種行型(每小區種8行,株距5.0cm),B-170cm的b種行型(每小區種9行,株距5.5cm):C-180cm的a,b種行型(每小區12行,株距6.5cm)D-190cm a,b種行型(每小區12行,株距6.0cm),c種行型(每小區9行,株距5cm)。及62年秋作(北港),A-160cm的a種行型(每小區12行,株距7.5cm);C-180cm的a行型(每小區12行,株距6.5cm)等子實產量的超過對照區。但超過數量不大。

各種行型處理間平均產量以兩行道間種4行者最多,其次為3行,最差者為2行各種行型處理株距以6.5cm以上者產量較高,株距愈小產量愈低。


Study on Row Patterns of Peanut for Mechanization Cultivation

H. C. Mao, C. S. Hsu

Summary

        This study divided into four tests according to machine width 160 cm, 170 cm, 180 cm, and 190 cm, has three row patterns designed every test, and the conventional planting distance (30cm × 10 cm) as check. Part of the test land is spared for machine paths to enable machine operation in farm.

       The average of all three row patterns every test, whether spring crop or fall crop, of no. of branches, No. of pods and weight of pods per stand decreases, in comparison with checks, on the contrast, the average of plant height increase.

       The average of seed yields per hectare decreases also, besides few which yield is over checks.

       The ratio of machine paths and blocks that seeds are planted between tow machine paths is 4:3 or 5:4 (n+1:n) in a plot. But the n→∞, if cultivation in large area, then n+1:n=1:1, the extra-one machine path may be omitted.  Assume here is 10 hectares of land for counting yield of seed, according to n+1:n=1:1, those yields of seed per 10 hectares are more than that of checks as follows:

Fall crop, 1972 at Tainan: B-170 cm, a-row pattern, C-180cm, B-row pattern.

Spring crop, 1973 at Tainan: C-180 cm a-row pattern.

Fall crop, 1973 at Tainan: A-160 cm a, b, c-row pattern, C-180 cm, a-row pattern.

       Although these are more than that of checks but little.

       The row pattern blocks that planted four rows between tow machine paths produce the highest yield per unit, 3 rows secondary, 2 rows, the least. And the row pattern blocks that possess planting space between two plants over 6.5 cm are better for yield per unit, the more the planting space is, the more the yield per unit is in this study.
