Five notes of summer stubble cucumber live broadcast

Miao Qi Miao Zhuang is an important foundation and guarantee for high quality and high yield of cucumber, so how can the summer stubble cucumber seedlings be sturdy? The author believes that the following aspects should be noted:

1. Pay attention to balanced fertilization

The organic fertilizer (chicken manure, pig manure, cattle and sheep manure, etc.) used in the land preparation must be fermented to fully rot, it is best to apply it in advance. The amount of base fertilizer used in chemical fertilizers should not be too large. Generally, 30-40 kg of compound fertilizer is applied per mu of cultivated land, and appropriate amounts of biological bacterial fertilizer and trace element fertilizer are applied. In addition, when applying all fertilizers, spread them evenly to avoid the emergence or burning of seedlings due to improper use of fertilizers.

Second, pay attention to the flat surface

The unevenness of the border surface will cause drought and waterlogging when watering, resulting in inconsistent cucumber emergence. Therefore, after shaving the back of the ground, you should use an iron harrow to hug it along the border again, so that the border surface is smooth and free of roughness.

Third, pay attention to the same depth when sowing

The different shades of summer stubble cucumbers are the main cause of uneven seedlings. If they are planted too deep, they will cause slow emergence, and they will not be sprouting after emergence, and they are also susceptible to disease infection. If they are too shallow, they are easy to sun. The buds cause a lack of seedlings, and the most suitable depth for summer direct seeding of cucumbers is 1-2 cm.

Four, watering should not be too fierce

When stubble cucumbers are poured in summer stubble, the amount of water should not be too large or too strong, because when the water is too large or too strong, it will cause the seeds sown at the border of the border to be washed by the water and thicken the silt to cover the soil. There is no seedling or the seedling emerges slowly because the seed is covered with too thick soil. You can pour 2 to 3 borders at the same time according to the usual water volume to reduce the impulse of water flow.

Five, pay attention to prevent pests and diseases

Diseases and insect pests of cucumber roots such as root rot, wilt, root-knot nematodes and other underground pests can also cause uneven cucumber seedlings, even lacking seedlings and breaking ridges. Therefore, vegetable growers should buy coated seeds as much as possible to avoid repeated stubble planting, and irrigate roots with avermectin and phoxim 1500 times to prevent and control underground pests.
