Last Updated: 2024/11/06, Cotton is a straight root crop, the main root is deeply embedded in the soil, and it is a drought-tolerant crop. The period from budding to boll opening is the key period of water demand. 1. Conventional irrigation: the whole growth period is irrigated 3-4 times, the first irrigation is in the budding stage, that is, in mid-late June, the second irrigation is in the full bloom stage, that is, the middle of July, the third irrigation is in the flower and boll stage, that is, from the end of July to the beginning of August, if the weather is dry or sand leakage can be done again. If there is a lot of rainfall, if there is no drought, it can no longer be watered. The irrigation quota, in addition to 120 square meters of water per mu, will be irrigated every time during the growth period.

If there is a lot of rainfall, no drought can no longer be watered, the irrigation quota, in addition to 120 square meters of irrigation per mu, irrigation 60 square meters per mu during the growth period. The irrigation quota is 360 square meters per mu. Using small border irrigation, the suitable area of small border is 0.2-0.3 mu.

2. Drip irrigation under plastic film: the area of drip irrigation under plastic film in our county is large, so we should irrigate scientifically according to the following irrigation scheme to ensure the water-saving effect of drip irrigation.
