Chili drip irrigation

Release Date:

2019-11-02

Chili peppers exhibit semi-drought tolerance under drip irrigation, but this does not mean they can be left unwatered or watered only sparingly. On the contrary, throughout their growth cycle, irrigation should be adjusted promptly in response to changes in developmental stages. During the seedling stage, water application should be carefully controlled; from the setting of the first flower cluster through the peak fruiting period, higher water demand requires frequent irrigation. During the growing season, the order of nutrient uptake is potassium > nitrogen > calcium > magnesium > phosphorus. Once the first flower cluster begins to set and the fruits start to enlarge, nutrient uptake increases rapidly, with nitrogen, potassium, and calcium accounting for approximately 70%–90% of total uptake. Starting from the fruit-expansion stage, magnesium uptake also rises markedly. As soon as August arrives,

Chili drip irrigation

Chili peppers exhibit partial drought tolerance, but this does not mean they can be left unwatered or watered only sparingly. On the contrary, throughout their growth cycle, irrigation should be adjusted promptly in accordance with changes in their developmental stages. During the seedling stage, water application should be carefully controlled; from the setting of the first flower cluster through the peak fruiting period, greater water availability is required to ensure regular irrigation; and during the vegetative phase, the order of nutrient uptake is potassium. Nitrogen > calcium > magnesium > phosphorus. Once the first inflorescence begins to set fruit and the fruits start to enlarge, nutrient uptake increases rapidly, with nitrogen, potassium, and calcium accounting for approximately 70% to 90% of the total uptake. Starting from the fruit-expansion stage, magnesium uptake also increases markedly.

As soon as one enters In August, when pepper fruits are expanding, traditional flood irrigation often leads to gray mold, causing fruit rot and significantly reducing both flavor and yield—a long-standing challenge for pepper growers. To address this issue, China has continuously developed scientific irrigation technologies; field trials have demonstrated that drip irrigation can increase pepper farmers’ income by RMB 3,000 to 4,000 per mu, bringing total earnings per mu to over RMB 10,000.

After preparing the chili field, follow the planting specifications. Create raised beds 1 meter wide. To facilitate later installation of the irrigation network, first divide the field into 100-meter-long sections, then excavate a 50-centimeter-wide service aisle in the center, so that each bed is 50 meters long (including the 25-cm service aisle). Apply sufficient base fertilizer, and plant two rows per bed. After planting, begin laying the irrigation network: install a main supply pipe along the center of the service aisle, connecting its inlet to the outlet of the irrigation pump; at the location corresponding to each pepper row, fit a valve-equipped connector on the supply pipe and extend another section of supply pipe directly to it; then connect one drip line on each side of the main pipe, with one drip line per pepper row, approximately 50 meters in length, and seal the end of each drip line. Once the drip lines are installed, use small bamboo strips every 60 centimeters to form semicircular arches that hold the drip lines in place by inserting them into the soil; the distance between the top of each arch and the drip line when the line is fully filled with water should be about 0.5 centimeters. This arrangement ensures that, after mulching with plastic film, the film does not adhere too closely to the drip lines, preventing soil and sediment from clogging the drip holes. Upon completion of these steps, proceed with mulching the beds. If fertilization is required, simply dissolve the fertilizer in water.

Drip irrigation Not only does it reduce electricity consumption for irrigation, but it also significantly cuts down on labor in areas such as work hours, pest and disease control, and topdressing, leading to a marked increase in efficiency. Aside from the initial capital investment in facilities, each 667m2 Costs can also be saved per crop. 399 yuan.

Drip irrigation It has truly achieved the goal of cost reduction and efficiency improvement, reducing seasonal expenditures in terms of labor and time. 399 yuan per hectare 2 Moreover, due to the advanced nature of this technology, water and fertilizers can be precisely applied at specific locations, significantly enhancing their utilization efficiency. As a result, peppers exhibit robust growth and development, leading to increased yields. The resulting economic, social, and ecological benefits are highly significant.
