俗话说,“三分种植,七分管理”,良好的管理是苗木成活的关键。那么,苗木在后期养护阶段,又有哪些需要重视的地方呢?
As the saying goes, "three planting, seven management", good management is the key to the survival of seedlings. So, what should be paid attention to in the later stage of seedling maintenance?
一、栽后注意采取措施提升地温
1、 Take measures to improve the ground temperature after planting
由于春季气温回升速度较快,而地温回升的速度相对较慢,在苗木栽植后,容易造成发芽快,生根慢的现象。所以,要注意采取措施,进行地温的提升,以使根系快速生长,这样更有利于苗木的栽后真正成活,避免假活现象。常采用的方式有覆盖地膜、增施热性有机肥,如羊粪、马粪。
Due to the rapid rise of temperature in spring and the relatively slow rise of ground temperature, it is easy to cause the phenomenon of fast germination and slow rooting after seedling planting. Therefore, we should pay attention to take measures to improve the ground temperature, so as to make the root system grow rapidly, which is more conducive to the real survival of seedlings after planting and avoid false live phenomenon. The common methods are mulching with plastic film and increasing the application of thermal organic fertilizer, such as sheep manure and horse manure.
二、栽后忌过频浇水
2、 Avoid watering too often after planting
春季苗木栽植后,要注意对土壤水分的合理控制,过度的浇水不仅不利于苗木成活,反而会加速根系的腐烂。主要原因是,春季过度浇水,常造成土壤温度提升受到抑制,使温度难以满足生根需求。另外,过度浇水,则造成土壤含氧量降低,根系进行无氧呼吸,导致根系腐烂。这也就是我们常常发现,栽后的苗木不是旱死的,而是浇死的主要原因。
After planting seedlings in spring, we should pay attention to the reasonable control of soil moisture. Excessive watering is not conducive to the survival of seedlings, but will accelerate the decay of roots. The main reason is that excessive watering in spring often inhibits the rise of soil temperature, making it difficult for the temperature to meet the needs of rooting. In addition, excessive watering will reduce the oxygen content of soil, and the root system will carry out anaerobic respiration, resulting in root rot. This is the main reason why we often find that the seedlings after planting are not killed by drought, but by watering.
