Grain Rain season has come, can we still grow cucumbers in the open air in the north now?

The weather is getting warmer and warmer, and friends who like to grow vegetables can take action now. People who like to grow scientifically rich vegetables. I haven't been busy in the garden these days. A friend asked me if I could grow homemade vegetables such as cucumbers and pods this season. Cucumber and pod are the most common vegetables in farmyard. A small piece of land is reclaimed every year in the yard of the hometown of developing agriculture through science and education, and these two vegetables are planted on this land. Now this season, my hometown is in the Central Plains, and the temperature is stable at around 15 degrees during the day. In this temperature condition, many vegetables can be planted, and the rape in the field has begun to blossom. Can cucumbers and pods be planted in the open field now? First, let's look at two temperature requirements for germination. Soybean is a kind of heat-resistant vegetable, and likes a warm growing environment. The optimum temperature for seed germination is about 25 degrees. Too low temperature will affect the germination rate and growth rate of seeds. Look at the cucumber. Cucumber also likes warm growing environment. The optimum growth temperature is about 20℃ to 25℃. When the daytime temperature is lower than 15℃, it will be affected by cucumber growth.

Under the above circumstances, it is too early to grow cucumbers and pods in the open field in northern China. If it is in the south and the temperature can be stabilized at around 20 degrees during the day, then planting in the open field is not a problem. However, if you are in the north like me, you will have to wait a little longer. It is estimated that these two vegetables can be planted in public around Tomb-Sweeping Day. Now that these two vegetables are mentioned, let's talk about the main points of planting these two vegetables through science and education.

After the solar terms in Grain Rain, it rained harder and harder, and became a white valley. With sufficient and timely rainfall, cereal crops thrive. In the south of Grain Rain, "Huayang sings", catkins fly away, rats cry at night, peonies support them, cherry red, and natural scenery notices: late spring. At this time, the temperature in the south rises rapidly. Generally, the average temperature rises from 20 to 22 in late April, which is more than twice as high as that in mid-April, except for parts of northern and western South China. In the eastern part of South China, high temperature of over 30 occurred in 0/0 ~ 2 days, and heatstroke began.

After Grain Rain, rainfall increased, which provided sufficient water for crops growing in spring and created conditions for spring ploughing. This is a good season for planting early rice, cotton, spring corn and other crops. It is necessary to insert early rice in time, grab green sowing surface and spring corn, prevent crop diseases, and make preparations before raising spring silkworms. Qingming and Grain Rain are also the peak periods of tea picking, so we should organize our manpower and don't miss a good opportunity.
