The 7-day growth process and record of green beans is as follows:

1, Day 1: I put eight intact green beans into a bowl, soaked them in water, and placed the bowl in a ventilated area of the balcony.

2, the second day: soaked for a day of green beans have basically peeled off the skin, the body of the beans in the middle of the split, grew about 1 cm of roots. Then, I will pour the bowl of water, in the bottom of the bowl spread a layer of water-absorbing paper towels, the green beans on the paper towels, and then covered with a layer of wet paper towels.

3, the third day: yesterday, the skin off the mung beans are still tender yellow tender yellow, but today has become green, most of the mung bean sprouts root length reached 3 cm, a small part of the 2 cm, only one root length 1 cm. I watered them, tomorrow, how many centimeters will the mung bean roots grow?

4, the fourth day: today, the longest mung bean roots reached 4 cm, the shortest only 2 cm, the roots gradually become white, transparent, and, 2 pieces of turquoise green leaves from the mung bean cracks drilled out, sprouting!

5, the fifth day: mung bean sprouts grow fast, the most upright 7, 8 cm high, most of the 5, 6 cm high, the smallest only 3 cm high. Cracked mung beans grow in the middle of the bean sprouts, has begun to dry. The young leaves are also growing and darkening in color.

6. Day 6: The roots of the mung beans are getting longer and longer, and some small root whiskers have grown. Part of the bean sprouts are already 10 centimeters high, most of them are 8,9 centimeters high, and 2 of them are only 4,5 centimeters high. The leaves have grown and the lines are clearer. The mung beans are so wilted that they are about to leave the mung bean sprouts.

7, the seventh day: most of the roots of the mung beans "hide" under the paper towel, the highest mung bean sprouts have grown to 12, 13 cm, the smallest is only 7 cm high, the mung beans are a little blackened, the leaves have become larger.

Growth habit:

Mung beans like temperature, suitable for the emergence and growth of the temperature of 15 to 18 degrees Celsius, during the reproductive period need higher temperatures. Germination starts at 8 to 12 degrees Celsius. During flowering and pod formation, temperatures of 18 to 20 degrees Celsius are generally optimal.

Higher temperatures and excessive stem and leaf growth will affect flowering and podding. Mung beans are intolerant of frost in the later stages of reproduction, and when the temperature drops below 0 degrees Celsius, the plant will freeze and the germination rate of the seeds will be low.
