免耕vs.耕作蔬菜园艺
当谈到免耕或在花园区域耕作时,有几种不同的意见。当讨论耕耘和免耕的区别时,这完全取决于你的个人喜好,你是否想在你的花园里做。免耕园艺是指不干扰花园土壤,除非你把种子放在花园里。而在菜园中耕作意味着你准备和耕作土壤种植的工具,如一个tiller两轮锄,或霍斯马镫锄。
免耕园艺的利与弊
免耕的第一个好处是整体保墒。因为你没有耕作土壤,土壤层不破碎,这提供了花园区域的能力,以保持更好的水。免耕园艺的另一个主要好处是控制侵蚀。在大雨期间,免耕可以减少土层的流失。第三个好处是保持了菜园土壤的生物学特性。然而,在某些气候条件下,土壤中有机物质更丰富的地区,这可能更加重要。免耕园艺的最后一个好处是菜园里不埋杂草种子。在花园中耕作时,杂草种子会被种植到土壤中,但在免耕的情况下,杂草种子会留在花园土壤的顶部。虽然,在花园区域免耕也有一些好处。对于免耕花园来说,第一个缺点是杂草数量的增加。 Weed pressures like nutgrass can cause serious problems because they have to be frequently cultivated in order to eliminate them completely from growing in the garden area. Another probably with weeds in a no-till garden is the limited ways to handle and control them. The second downside is during rainfall it does not stick to the soil meaning the water does not absorb into the soil without cultivation. The next major downside is the decrease in good seed germination in the garden soil. In the garden, when the area has been tilled the soil can then provide better seed to soil contact which is needed for good germination. Along, with poor seed germination, no-till takes much more time and energy. This can be an issue caused by mulching because you have to remove it to replant and it can tie up nutrients in the soil. The last downside of no-tilling in the garden area is the reduction of soil compaction. For some crops in the garden like carrots, it can be harder for roots to penetrate in the soil.
展示和讲述环节
在“展示和讲述”环节,温室里满是秋季花园的移植植物。他们试着在观众面前品尝玉米芯果冻。他们也讨论了一些即将推出的洋葱品种。
观众问题部分
在本周的问答环节中,他们将回答关于间距和肥料需求的问题老虎羽衣甘蓝和所有顶级的萝卜。以及他们的花园土壤中硝酸盐是否积累。特拉维斯提到,羽衣甘蓝和萝卜的肥料需求是相似的,都是种植前每100英尺一磅。在种植羽衣甘蓝时,特拉维斯将它们间隔一英尺,分成两行,中间用滴灌。格雷格提到,为了避免硝酸盐在土壤中积累,你不应该超过你需要的量,直接放在植物需要的地方。
