Lingnan dry slope farmland soil moisture and improve water use efficiency measures
Pine Ridge bath fertilization and other repressive measures to maintain favorable soil moisture and improve the quality of planting. But the fall soil preparation is the key to timely and ensure quality. (Table  capsule 3'm floating pile plate Will the entire ridge and snapped poultry ■ tt soil moisture over the year! Treatment I soil depth. m-'F are =! 0 ~ 30z. ss good ridge falling wilt:; l ;}!}; a}. seI autumn stems I. l} I din so exhausted and so li1O,[link widoczny dla zalogowanych], 32 a, by} II 2. Planter. Deduction of local cup of traditional species, thick soil volume, soil moisture run faster and use plug-in planter, ground-breaking small amount of moisture is also running low, the seeding layer of water after sowing were higher spear buckle species. (Table 4) capsule four kinds of sowing machines and debit the comparison of soil moisture after sowing sowing sowing methods to be the top cm depth tools 0 ~ J0110 ~ 20 {0 ~ 20I (and] plow deduction species J4, 09:20.75 J7, 42112 .98 ll5.80J4, 28Il8.O2 seeder machine hi l oath l5, 34l22.04 {.59 Ll4, 28j21.37; l7.8304.603. multicast suppression after the re-use the soil after planting to suppress creation of an appropriate soil compaction degree, there are clear references to the role of entropy according to our test results soil moisture, suppress the control wheel with iron repression (re-repression) surface soil water content than the pressure of an increase of 4.3 ~ 5.7ram, increased 32.3 ~ B8 .4, with the suppression of the local operation Gunzai (light suppression), table entropy increase of only i.7 ~ 2.5ram, before this pressure is only increased by 14.3 ~ 21.2. significantly lower than the weight of the soil moisture for water suppression effect, severe spring drought years, re-suppression effect is particularly evident .4. cultivator leave loose. into the rainy season or crop seedlings, shovel tread the furrow end table subsoiling to break the plow pan, thick living soil, can enhance soil permeability, accumulation of more rain, according to Ba j determined by the Department of eddy columns loose their permeability coefficient ratio is not high subsoiling 0.42mm / min, so that the same rainfall conditions, the comparable Subsoiler not deep Song of the savings more rain. According to our July 1987 the results of a determination after the rain: Subsoiler 0 ~ 50ci'll increased soil water after rain Qiang 35.55mm,[link widoczny dla zalogowanych], did not loose the water bath cultivators increased by 27 .18 i'llm, Subsoiler subsoiling more water than non-8.37n 'lm. (c) by fertilizer, soil fertility, water by fertilizer. completed in the dry arid regions,[link widoczny dla zalogowanych], increase crop yield major limiting factor water, fat lies. This view of the current drought has played a major agricultural production slope guide our point groups in three villages of fertilizer increased fertilizer experiment also proved that, there are obvious increase yield, reduce water consumption coefficient , played water by fertilizer, improve water use efficiency results (Table 5). capsular shoot 5 different financial Lu secluded down on Mexican maize tung wood ring at the conversion rate of urea fertilizer urea l feces and fruits pilot control element entry f7.5 kg of organic manure 02000 kg reasonable 'head, j7.5 J5 kg 02,000 kg kg yield (kg / mu, 303524.16lO.4I367.46.57lJ.8 peace village water consumption factor 1 .580.920.79 lJ.310.780.B7 yield (kg / mu) 284 {406.4478.4I339.2506.2558.7 beam deposited J.6 village water system sound JJ.18J.0OIJ.420.950. 86 yield (kg / mu) 518.5I537.1537.1I685.2777.8926.2 far Village Water consumption coefficient 0.9210.890.890.710.620.52 Note; ① pilot villages are in the village dam i ga . @ control: no fertilization. @ Kang Su containing nitrogen,[link widoczny dla zalogowanych], 46 Sima, 6 pounds per acre kinds of fertilizer, top dressing before the rest of tasseling. (port) in accordance with the characteristics of sloping land, Taiwan, Feng Li turn layout and variety of drought-tolerant. dry slope slope cultivated land is not ugly there qH obvious differences in soil fertility and soil moisture requirements of different crops to different fertilizer conditions. Mi Valley, sorghum, transpiration coefficient between 250 and 350, drought resistance, yield stability, and was originally a local tradition the main crops. in recent years in some areas and farmers, regardless of slope land agriculture, particularly the characteristics and current conditions customer, one-sided pursuit of high-yield, high value, the excessive consumption of fat consumption expanded planted more corn, sunflower cultivation area, Crops disrupted and damaged the wheel ashamed system lurking cloth production steady,[link widoczny dla zalogowanych], declining soil fertility crisis. boast a variety of post-slope slope should be} Mi Valley and other drought-resistant crops should be peaceful to the lower slope corn, sunflower, soy-based, so the garden should be a result of crop system, the Taiwan manager layout, proper place to ensure the long-term food production stable and high yield. * 19 *
