石榴有甜酸之分 ,甜者如蜜 ,酸者酸中带甜 ,生津止渴 ,深受人们喜好。如何区分甜石榴和酸石榴呢 ?一般甜石榴果嘴合拢 ,皮色粗糙 ,叶片短宽 ,树枝脆而易断。酸石榴果嘴多张开 ,果形规整 ,皮色光亮 ,叶片狭长 ,树枝韧而不易折断。石榴适应性广 ,在干旱与半干旱地区 ,冬季不低于 - 2 0℃都能栽种。对土壤要求不高 ,若土壤过肥 ,反而花多果少 ,枝条徒长 ;土质过差 ,又会使果实品质不佳。石榴繁殖简易 ,主要以扦插、压条和分株为主。春季发芽前 ,选择一年生健壮枝条 ,剪成 30~4 0cm ,斜插在疏松的土壤中 ,上留 2~ 4个芽眼 ,适时浇水 ,保持土…  相似文献

甜桑是子长及周边各县古老的桑树品种,是陕北黄土丘陵沟壑区干旱、寒冷、贫瘠的环境条件下自然选择和人工选择保留下来的地方特色品种,以乔木桑养成。陕甘宁边区时期,子长境内有零星桑树22 300株。2019年秋冬季,子长市蚕桑开发中心对本地自然生长的甜桑百年老树进行了专门调查,发现树龄在80年以上的仅剩498株,分布于涧峪岔镇、南沟岔镇等8个乡镇3个便民服务中心的25个村落。文章提出了建立甜桑种植资源圃、接穗园、苗圃,建设甜桑中高干示范园、川台地密植桑园,成立桑树种植资源保护站,发展甜桑生态乔木桑,开发蚕桑高附加值产品等意见和建议。  相似文献

In experiment 1, 6 pregnant mares received a concentrate that contained a trace mineral premix that provided 14.3 mg Cu, 40 mg Zn, 28 mg Fe, 28 mg Mn, 0.08 mg Co, 0.16 mg I, and 0.16 mg Se/kg concentrate (group A). Seven mares received the same concentrate plus 502 mg Zn and 127 mg Cu once daily (group B). No differences (P > .05) in foal growth data, or Cu, Zn, and Fe concentrations of mare milk, mare serum, or foal serum were observed. In experiment 2, 6 pregnant mares received the same concentrate as group A (group C), and 8 mares received the same concentrate fortified with 4× the trace mineral premix (group D). Group C mares had higher serum Zn concentration at 1 day (P < 0.01) and 56 days (P < 0.04). Group C mares had higher milk Fe concentration at 28 days (P < .01), and group D mares had higher milk Cu concentration at 56 days (P < .01). Group C foals had higher serum Cu concentration at 14 days (P < .03). The results from this study provide no evidence to indicate that supplementing late gestating and lactating mares with higher dietary trace mineral levels than those recommended currently by NRC has any influence on foal growth and development, or on the Cu, Zn, and Fe concentrations of the mare milk, mare serum, or foal serum.  相似文献

Breed differences for weight (CW), height (CH), and condition score (CS) were estimated from records (n = 12,188) of 2- to 6-yr-old cows (n = 744) from Cycle IV of the U.S. Meat Animal Research Center's Germplasm Evaluation (GPE) Program. Cows were produced from mating Angus and Hereford dams to Angus, Hereford, Charolais, Shorthorn, Galloway, Longhorn, Nellore, Piedmontese, and Salers sires. Samples of Angus and Hereford sires were 1) reference sires born from 1962 through 1970 and 2) 1980s sires born in 1980 through 1987. The mixed model included cow age, season of measurement and their interactions, year of birth, pregnancy-lactation code (PL), and breedgroup as fixed effects for CW and CS. Analyses of weight adjusted for condition score included CS as a linear covariate. The model for CH excluded PL. Random effects were additive genetic and permanent environmental effects associated with the cow. Differences among breed groups were significant (P < 0.05) for all traits and were maintained through maturity with few interchanges in ranking. The order of F1 cows for weight was as follows: Charolais (506 to 635 kg for different ages), Shorthorn and Salers, reciprocal Hereford-Angus (HA) with 1980s sires, Nellore, HA with reference sires, Galloway, Piedmontese, and Longhorn (412 to 525 kg for different ages). Order for height was as follows: Nellore (136 to 140 cm), Charolais, Shorthorn, Salers, HA with 1980s sires, Piedmontese, Longhorn, Galloway and HA with reference sires (126 to 128 cm). Hereford and Angus cows with reference sires were generally lighter than those with 1980s sires. In general, breed differences for height followed those for weight except that F1 Nellore cows were tallest, which may in part be due to Bos taurus-Bos indicus heterosis for size.  相似文献

A simple two step procedure for the isolation of caprine, ovine, bovine, equine, canine, porcine and human peripheral blood granulocytes is described. After enrichment of granulocytes by centrifugation, contaminating erythrocytes are lysed hypotonically. Recovery, purity, and viability of the granulocyte suspensions are determined. FACScan analysis of the cell suspensions measuring cellular size by forward and sideward light scatter is compared with the corresponding analysis of whole blood leukocytes. Constituencies of the isolated cell suspensions and loss of granulocyte subpopulations through isolation procedure is discussed with regard to granulocyte function assays.  相似文献
