作者以桑树、栗树、桉树木屑为培养料原料,研究不同木屑对浙香6号香菇的菌丝发育、子实体经济性状和产量的影响。试验结果表明,在智能控温养菌棚内养菌,桑树、栗树、桉树木屑培养料对香菇菌丝生长发育的影响差异不大,对子实体性状、产量的影响略有差异。其中,栗树木屑培养料处理香菇的菌盖相对较大、较厚,桑树木屑培养料处理香菇的单棒产量、生物转化率相对较高,桉树木屑培养料处理香菇的子实体性状、产量表现稍差,但菌丝发育速度较快,第1潮菇的采收期较其他2种木屑培养料处理提早1～2 d。综上所述,桑树、栗树、桉树木屑均可作为袋栽香菇的培养料,但使用以桑树、栗树木屑为主的培养料栽培香菇效果较好。 相似文献

香菇棉秆粉代料栽培规模化生产试验 总被引：6，自引：0，他引：6
在实验研究的基础上,成功地进行了棉秆粉代料栽培香菇的规模化生产试验.试验结果表明,棉秆粉代替木屑栽培香菇是完全可行的,但出菇后期营养不足、容易散袋,导致出菇期短,产量低.若在培养料中加入一定量的木屑,则可调节培养料的营养结构,增强料袋的紧实度,提高保水性能,菌丝生长快,香菇产量高,花菇率高.试验表明,培养料中木屑含量在20%左右时,香菇产量最高,效益最佳. 相似文献

红富士苹果果实大小分布的早期预测研究 总被引：3，自引：0，他引：3
以盛花后30～50d果实横径的日平均生长量(DFGR)作为预测指标,根据预测指标与采收时对应果实横径之间的线性回归方程y=153.571x+73.492(x为盛花后30～50dDFGRmm/d,y为采收时果实横径mm)来预测采收时果实的平均横径。同时根据红富士苹果采收时果实大小的分布获得以平均果实大小u为对称轴呈正态分布的曲线方程F=1/犤4×0.556×(2π)0.5犦×e-犤(x-u)^2/(2×0.556^2)犦(F为某一等级的果实分布频率,x为相应等级的果实横径),根据所获得的正态分布的曲线方程来预测采收时不同大小级别果实所占比例。连续3个生长季节预测分布状况和实测分布状况的比较结果表明:利用正态分布的曲线方程来预测富士苹果果实采收时不同大小级别分布,优于直接采用盛花后30～50dDFGR来预测采收时单果果实大小获得的不同果实大小的级别分布,且与实测的采收时果园果实大小分布的吻合度较高。 相似文献

从采集自云南省临沧市的野生子实体上分离纯化获得菌株YAASM4210,采用形态学法结合ITS序列分子法鉴定为花脸香蘑(Lepista sordida)。对该菌株生物学特性进行研究并对其栽培料进行筛选。试验结果表明:该菌株菌丝生长的最适温度、培养基pH、光照条件、碳源和氮源分别为25℃、6.0~7.0、黑纸包裹、可溶性淀粉和蛋白胨。该菌株在4号配方培养料(40%新鲜牛粪,20%草坪粉,20%米糠,18%木屑,1%蔗糖和1%石膏)上生长优于其它参试培养料:菌丝萌发(2d)、封口(12d)、满袋(40d)以及子实体的采收(9d)均用时最短,头潮菇产量最高(每袋21.1g),但覆土后出菇时间(42d)最长。相对于野生子实体,人工栽培子实体菌盖的紫色减弱,采收后紫色消失较快。 相似文献

The effect of four times of limb girdling on fruit and tree response was examined on ‘Mayfire’ nectarine (Prunus persica (L.) Batsch). Girdling prior to Stage II of fruit growth reduced the lag phase associated with Stage II, and caused peak fruit growth rates to occur earlier in the season than on later girdled or ungirdled trees. Optimum response was obtained by girdling prior to Stage II, when fruit seed length was approximately 10 mm. Girdling at this time increased fruit weight by 22.5% and more than doubled the percentage of fruit in the largest three size categories. Maturity, measured as soluble solids concentration, was increased by 42%. Shoot extension growth was reduced only by early girdling. Leaf weight per unit area was increased, and leaf nutrient concentrations were decreased by all girdling treatments. Leaf conductance to water vapour (g,) was not affected when measured 8 days prior to and 78 days after harvest. Fifteen days after harvest, g, was decreased in all girdling treatments. 相似文献

SummarySpurs of ‘Nijisseiki’ pear (Pyrus pyriflora Nakai) were allowed to assimilate 10033;CO2 at 87.d after anthesis (DAA) and at 108 DAA during the period of rapid fruit growth. Then the spurs were sampled periodically until fruit harvest time to trace the time course and amount of movement of assimilates from spur leaves to individual organs in the spur. The amount of 10033;C absorbed by fruit within 3.d after labelling was constant until harvest, regardless of the labelling date. However, the total amount of 10033;C in the spur decreased continually until harvest.Of the total amount of 10033;C recovered in the spur labelled at 87 DAA, by harvest, 43.2% of 13C was found in the fruit flesh (cortex of receptacle), 5% in the core (pith of receptacle 1 pericarp 1 seeds), 5.6% in spur stem, 5.4% in the source leaves, and 40.8% was respired and exported from the spur. Of total amount of initial 10033;C labelled at 108 DAA, at harvest, the proportion of 10033;C translocated to flesh, core, stem, respired, and remaining in leaves was 61%, 6.1%, 3.0%, 24% and 5.4%, respectively. Photosynthates fixed by the spur early in the rapid growth stage of the fruit contribute more to the formation of starch and structural materials and less to solublecarbohydrates in fruit than do those fixed later. 相似文献

本研究以遵椒系列品种为材料,探索其单果质量变化规律、常规测产校正系数和折干率。结果表明:①从8月上旬始收期开始,每晚收1d,遵椒1号单果鲜质量会下降0.1534g,单果干质量会下降0.0132g;遵椒2号单果鲜质量会下降0.0905g,单果干质量会下降0.0157g;遵椒3号单果鲜质量会下降0.0882g,单果干质量的变化不会随采收期的推迟而显著下降。②由于遵椒系列品种前期营养充足,病虫害轻,单果质量较大,商品率高,而后期长势渐衰,病虫害加重,商品率下降,单果质量变小,从而导致常规测产产量与实际采收量相差较大,常规测产产量乘上校正系数才能得出接近于实际的产量,通过试验,遵椒1号的校正系数为0.4782、遵椒3号的校正系数为0.541、遵椒3号的校正系数为0.629。③遵椒系列品种辣椒折干率基本遵循前期低后期高的规律,遵椒1号平均为23.81%,遵椒2号平均为25.23%,遵椒3号平均为25.82%。 相似文献

Pepper (Capsicum annuum L.) production is normally carried out under irrigation as the crop is very susceptible to water shortage. Deficit irrigation strategies in pepper for paprika could increase production and facilitate mechanical harvest and, at the same time, save water. We conducted a field experiment that imposed water deficits, either during ripening (T1) or throughout the season (T2), and compared them to a fully irrigated control (T3). Stem water potential varied from −0.6 MPa in T3, early in the season to −1.5 MPa in T2 prior to harvest. Applied irrigation water for T1, T2, and T3 was 456, 346 and 480 mm, respectively. Water deficits depress leaf area and biomass production but did not affect the proportion of flowers that set fruit. Dry fruit weight in T2 at harvest was 66% of T3, but did not differ significantly between T1 and T3. However, commercial yield (based on colour production) was significantly higher in T3 than in the other two treatments, as the late water deficits imposed in T1 delayed harvest. We concluded that water deficits, either sustained or applied at fruit ripening, required for mechanical harvest do not hasten ripening and are detrimental to commercial yields and that pepper plants should be well supplied with water until harvest for maximum paprika production. 相似文献

SummaryTo determine the anatomical basis for differences in fruit size in Japanese persimmon (Diospyros kaki Thunb.), the number and sizes of parenchymal cells were measured in four astringent cultivars and in wild D. lotus over a single season in Japan. Fruit weight at harvest correlated with the final number of parenchymal cells (r = 0.95*) and their size (r = 0.92*). There was also a correlation between fruit diameter and the number of cell layers at full bloom (r = 0.93*), which increased 1.7 – 1.9-fold during fruit development.The duration of cell division and the sizes of the cells at full bloom were similar among the cultivars, whereas mean parenchymal cell lengths increased by 7.7-, 6.7-, 5.4-, 5.0- and 3.8-fold from full bloom to harvest in ‘Otanenashi’ (average fruit diameter = 96 mm), ‘Hiratanenashi’ (77 mm), ‘Saijo’ (54 mm), ‘Tsurunoko’ (44 mm), and D. lotus (20 mm), respectively. The final size of tannin cells was larger in ‘Otanenashi’ and ‘Hiratanenashi’ than in the other cultivars, including the wild species.These results indicate that the size of fruit at harvest was determined by the number of cells at full bloom, and their expansion during fruit development. 相似文献
