Sesame, rice, peanuts, cowpeas, cucumbers, sweet potatoes and other crops can be planted on Labor Day. 1, Sesame: Spring sesame seeds are generally sown from late April to early May, summer sesame seeds are generally sown from late May to early June, and southern autumn sesame seeds are generally sown from early July to mid-July. 2. Rice: The sowing time of early rice is generally from the end of March to the beginning of April, the sowing time of middle rice is generally from the beginning of April to the end of May, and the sowing time of late rice is generally from the middle and late June.

First, sesame.

2. Sesame is a warm crop and needs high temperature. Generally, sowing is carried out when the ground temperature is stable at 18-20℃ and the temperature is stable at 3-4cm above 20℃. The lowest temperature of seed germination and emergence is 65438 02℃, and the suitable germination temperature is 24-32℃.

Second, rice.

The sowing time of mid-season rice is generally from the beginning of April to the end of May, and the mature harvest time is generally in the middle and late September. The sowing time of late rice is generally in the middle and late June, and the mature harvest time is generally in the middle and early June of 10.

2. Rice likes high temperature and humid environment. The temperature required for seedling germination is above 10- 12℃, and the suitable temperature is 28-32℃, the suitable temperature for long roots and buds is 25-28℃, the suitable temperature for seedling emergence is 20-25℃, the suitable temperature for tillering is 30-32℃, and the average temperature for ear differentiation is required to be.

Third, peanuts

1. Spring sowing: Spring peanuts are cultivated in the open field in Liaoning, Beijing, Hebei, Shandong, Henan, northern Jiangsu and northern Anhui. Generally, the sowing date is from mid-April to early May, and it is from April 10 to 25th in central and southern areas of Henan, Hebei, Shandong and Shaanxi.

2. Summer sowing: interplanting summer peanuts with wheat stubble in Beijing, Hebei, Shandong, Henan, northern Jiangsu and northern Anhui is generally carried out from mid-May to mid-June.

3. When the ground temperature at 5cm is stable above 15℃ for 5 consecutive days, sow peanuts. When the ground temperature at 5cm is stable above 12℃ for 5 consecutive days, sow small peanuts.

3. Autumn cowpea: usually sown in August-September.

4. The lowest temperature of cowpea seed germination is 8- 12℃, the suitable temperature for germination is 25-30℃, the suitable temperature for plant growth and development is 20-30℃, and the suitable temperature for flowering and pod setting is 25-28℃.

Five, cucumber

1. In the middle and lower reaches of the Yangtze River, cucumbers are usually sown in mid-March in spring and from late May to mid-June in summer. In the middle and lower reaches of the Yellow River, spring cucumbers are generally sown from mid-April to early May, and autumn cucumbers are generally sown from late June to early August.

2. Cucumber germination temperature is 25-30℃, suitable growth temperature is 18-32℃, suitable photosynthesis temperature is 25-32℃, and suitable pollen germination temperature is 30-35℃.

Six, sweet potato

1. The planting time of sweet potato is generally April-May, and the best sowing time is mid-May. The specific planting time depends on the ambient temperature.

2. After cutting sweet potato seedlings, the local average temperature should be kept above 15℃, and the shallow soil temperature should be above 17- 18℃, and the cutting time should not be too early or too late.
