The population density of root-knot nematodes in soil is significantly correlated with the damage degree on the host. Therefore, accurately, reliably and rapidly identifying and counting RKN in soil is critically important for the effective control of disease.

Root-knot nematodes ( RKN, Meloidogyne sp.) are harmful to the agricultural production in the worldwide.

根结线虫（Meloidogyne sp.）严重危害世界农业生产。

In conclusion, application of bio-organic fertilizers in field conditions could effectively control damages caused by RKN to muskmelon.

综上所述，施用生物有机肥能有效防治田间条件下根结线虫对甜瓜的危害。

Application of bio-organic fertilizers effectively reduced the population of the second instar larvae of RKN in soil and egg mass of RKN in roots;

施用生物有机肥可显著减少土壤中根结线虫二龄幼虫的密度和根中卵块的数量；

With the popularization of greenhouses cultivation, the RKN disease happens more extensively and severely than ever before.

随着温室大棚的推广，根结线虫病发生比以往更加广泛和严重。

The results show that there is a minimum distance from the cleavage to the precrack tip within which there are only micro-cavities instead of micro-cracks due to lower triaxiality of stress, and that the characteristic distance in RKR model does not exist.

结果表明，解理点距裂尖存在一个最小距离，在此距离内三轴应力度过低，仅能形成微孔而不能形成解理微裂纹，RKR模型中表述的特征距离并不存在。

Dynamic stress intensity factor impulse response curves are obtained. The dynamic initial fracture time, tf, can be received by RKR local stress fracture criterion. The material dynamic fracture toughness is successfully obtained from numerical simulation.
