Dry farming is mainly distributed in. What crops should be planted in dry land?

Dry farming is mainly distributed in the vast northern arid areas north of the Huaihe River in Qinling Mountains, followed by the hilly and mountainous areas in the south. Dry farming refers to the development of drought-tolerant, drought-tolerant and drought-tolerant crops farming system in drought-prone areas with little precipitation and no irrigation conditions, relying on natural precipitation and adopting a series of dry farming technical measures. When raising seedlings in dry land, we should seize the right time to grab moisture and sow, so as to achieve the effect of protecting seedlings and promoting strength. Generally, medium and small seeds can be sown from the vernal equinox to Qingming, and large and hard seeds can be sown in late autumn and early winter.

First, the main distribution areas of dry farming

1. Dry farming is mainly distributed in arid areas in the north, such as the vast northern areas north of Qinling Mountains and Huaihe River, followed by hilly areas in the south.

2. Dry farming refers to developing the farming system of drought-tolerant, drought-tolerant and drought-tolerant crops in drought-prone areas (arid, semi-arid and semi-humid) with scarce precipitation and relying on natural precipitation.

3. When raising seedlings in dry land, we should seize the appropriate opportunity to grab soil moisture and sow, so as to protect and promote strong seedlings. Medium and small seeds can be sown from vernal equinox to Qingming, and large and hard seeds can be sown in late autumn and early winter.

4. Crop rotation system should be adopted in dry land, because the nutrients in the soil will be consumed a lot after planting crops, and rotation can supplement some elements lacking in the soil, thus improving soil fertility.

Second, what crops should be planted in dry land?

1, corn

Corn is an economic crop and an annual tall herb. After planting, potassium dihydrogen phosphate can be sprayed at the later growth stage, which can improve the fruit setting rate.

2. Cotton

Cotton is a good cash crop, which is native to subtropical areas and has strong adaptability to the environment. The flowers of cotton are milky white and will turn dark red after flowering for a period of time.

Step 3: peanuts

Peanut belongs to the genus Panicum, which blooms and bears fruit from June to August and has a large number of pods. Peanut roots are rich in nodules, so decomposed cake fertilizer should be applied as base fertilizer when planting.

Step 4: potatoes

Potatoes belong to millet, and the requirements for soil are not strict, so they are suitable for planting in dry soil. Potato is tuber-shaped, generally rectangular, with a diameter of about 3- 10 cm.

5, sweet potato,

Sweet potato is a cash crop, and the requirement for water is not high. After planting, the drainage ditch should be dug before the rainy season, otherwise it will rot due to too much soil moisture.
