When is the Grain Rain Festival in 2022 suitable for planting cotton and sweet potatoes?

I believe everyone is familiar with this solar term in Grain Rain. Grain Rain in 2022 began on April 20th, 2022 10:24:07 and ended at 20:25:46 on May 5th, 2022. In 2022, on the 20th day of the third lunar month in Grain Rain, Grain Rain was the last solar term in spring. Obviously, we can find that at this time, the early planting of seedlings and the development of crops are in great need of rain. Therefore, the period from April 19 to April 2 1 every year is designated as the rainy season with abundant crops, and the rain during this period is extremely important for farming. This time is also the best time to sow.

Seasonal Cotton Planting in Grain Rain

There are many crops suitable for planting in Grain Rain, and cotton is one of them.

When the ground temperature at 1 5cm is stable above 16℃, it is suitable for sowing, and the specific time is generally around April 20 every year.

2. Before sowing, spread the cotton seeds on the straw mat and dry them for about 3-5 days to break the dormancy period of the seeds and improve the germination rate of the seeds.

3. When sowing, if it is a conventional cotton machine, the seed consumption per mu is about1-1.5 kg; If it is a hybrid cotton machine, the sowing amount per mu should be about 0.6kg, and the sowing depth should be about 3-4m, not too deep, because cotton cotyledons are hypertrophy and the topping ability is poor. Once it is too deep, it will easily lead to excessive nutrient consumption of seeds and weak seedlings.

Cotton has many uses, and the most common use is to make textiles.

Planting sweet potatoes in Grain Rain in season

Cold potatoes have many functions and medicinal effects.

1. Generally, cold potatoes are sown when the average temperature reaches 65438 02℃, and the specific time is about April to May every year.

2. Before sowing, you can soak the seeds in warm water for about 6 hours, then take them out and put them in an environment of 25-28℃ for germination (washed with warm water once a day), and sow when more than 50% of the seeds turn white.

3. When sowing, sow 8 rows per border (border width 1.2m), control the plant spacing at about 15- 16m, and plant about 8,000-9,000 plants per mu.

The above are the main points that should be paid attention to when planting cold potatoes.
