When will peanuts be planted in Linshui County, Sichuan Province?

1. Planting time of flower seeds in Linshui County, Sichuan Province: around March.

2. Introduction of peanut sowing in different regions:

Peanut is a kind of nut with abundant output and extensive consumption in China, also known as "longevity fruit" and "groundnut". China is distributed in Shanxi, Liaoning, Shandong, Hebei, Henan, Jiangsu, Jiangxi, Fujian, Guangdong, Guangxi, Guizhou and Sichuan. Foreign countries are distributed in Asia, Africa, America, Brazil, Egypt, Paraguay, Indonesia, Senegal, Sudan, Nigeria, Zaire and Argentina.

First, peanut planting time

Because of the different climatic conditions in different regions, peanut cultivation techniques are also different.

1, southern peanuts can be sown twice a year.

(1) Spring sowing is around March of the lunar calendar. Peanuts in spring bear more fruits and are fuller than peanuts in autumn.

(2) The sowing date of autumn peanuts is in early August when the altitude is low, and in late July when the altitude is high. If it is planted on a dry slope, it should be sown early to reduce the impact of autumn drought.

2. Multi-grain varieties are mainly planted in cold and cold areas in the north, and the frost-free period is short; Most common varieties are planted in peanut areas in northern China. The suitable sowing period in the northern peanut region and peanut producing area is mostly from late April to early May.

3, peanut knowledge expansion

Precautions:

1. Sowing spring peanuts in time can improve the utilization rate of land and light energy, make plants grow short and strong, with dense internodes, more branches, good root growth, more dry matter accumulation, more flowers and fruits, high full fruit rate and easy to meet the requirements of high yield and high quality.

2. Premature sowing, because the temperature is low, the seeds can not germinate normally, and the emergence is slow, which increases the chance of soil diseases and insect pests, and the emergence rate is low, and the seedling growth is poor, which affects the differentiation and development of flower buds; However, sowing is too late, and the southern producing area is in a high temperature and rainy environment, so peanuts are easy to grow and lodging, and there are few pods.

3. Peanuts in central and northern China, especially common peanuts, often encounter autumn drought and low temperature during pod setting and maturity, which affects pod development and nutrient accumulation, resulting in low full fruit rate, kernel rate and oil content, thus reducing yield and quality. When interplanting or sowing peanuts in summer, early-maturing varieties should be selected as the previous crops to avoid the yield reduction caused by late sowing of peanuts.

Growing habits:

1. Peanut is millet. It only takes more than one month from sowing to flowering, but the flowering period lasts for more than two months. Its flowers are solitary or clustered in leaf axils, ranging from 200 to thousands per peanut.

2. After flowering and pollination, the stalk of the ovary at the base of the ovary is constantly elongated, and a purple fruit needle grows from the withered flower tube. The fruit needles are rapidly elongated longitudinally. It grows upward first, and a few days later, the ovary stalk hangs on the ground. In the process of extension, the epidermal cells of ovary stalk lignified, which protected the young fruit needles from entering the soil.

3. When the needles are buried in the soil for 5 ~ 6 cm, the ovaries begin to lie horizontally, become fat and white, and hair grows on the body surface, which can directly absorb water and various nutrients for growth and development. In this way, seeds are formed one after another, the epidermis gradually shrinks and the pods gradually mature, forming the peanut fruit we see.

4. The above-ground flowering and underground fruiting are the inherent genetic characteristics of peanuts and the result of long-term adaptation to special environment. Peanuts like dark, humid and mechanically stimulated ecological environment when they bear fruit. These factors become indispensable conditions for pod growth and development. Therefore, in order to survive and spread seeds, it has to put its ovary into the soil to bear fruit.
