The invention provides a cucumber topping preventing method. The method comprises the following steps that 1, in the cucumber planting period, micro element liquid manure containing not smaller than 100 g/L of Zn+B is adopted, rooting and seedling survival of cucumber seedlings are promoted, and it is ensured that seedlings absorb micro elements; in the post-planting fruiting period, medium element liquid manure containing not smaller than 110 g/L of N and not smaller than 100 g/L of Ca+Mg is adopted, continuous growth of root systems is promoted, the plant growth vigor above the ground is promoted, and the resistance of cucumbers at the low-temperature period is improved; after the low-temperature period is reached, micro element liquid mature containing not smaller than 100 g/L of Zn+B,larger than 2% of N and larger than 3% of K is adopted, the low temperature resistance to cucumbers is improved, the root systems are kept to continuously grow, and meanwhile the combination of not smaller than 110 g/L of N, not smaller than 100 g/L of Ca+Mg, 30% of N, 10% of P and 10% of K is adopted for promoting growth vigor of root systems and plants above the ground. By cooperatively applyinglarge, medium and micro element manure, the whole resistance of cucumbers is improved, the growth vigor of root systems and plants above the ground is promoted, and therefore the cucumber topping phenomenon is prevented.
