(3) Rosette stage: refers to the period from the end of seedling stage to the complete unfolding of outer leaves and the beginning of Ye Gang's embrace, which is about 23-28 days. If it is an early-maturing variety, it can be shortened by 6-8 days.

(4) Grain-filling period: refers to the period from the beginning of the heart leaves to the fullness of the leaves, which is about 40-60 days, or about 25-30 days if it is an early-maturing variety.

2. Reproductive growth period

(3) Flowering period: refers to the time from the beginning of flowering to the basic flowering, about 30 days.

(4) Pod-setting period: It refers to the period from flower withering, pod growth to full seed development, about 20-25 days.

Third, the growth cycle of tomatoes.

It takes about 1 10 days to sow in March and April and harvest in July and September. In North China, it takes about 140 days to sow in June and harvest in late June. Sowing in February +0 1- 12, and harvesting in July. Sowing in the Pearl River region in August and September, and harvesting in June165438+1October.

1. Germination period: refers to the time from germination of seeds to the first true leaf of two cotyledons, which is about 7-9 days.

2. Seedling stage: refers to the time from the first true leaf to the first inflorescence, which is about 50 days, 60-80 days in cold season and 40 days in hot season.

3. Flowering and fruit-setting period: refers to the period from the first inflorescence to fruit-setting, which is about 15-30 days. If it is an early-maturing variety or cultivated at high temperature, it takes a short time.

4. Fruiting period: refers to the period from the first inflorescence to the end of production, which is about 3-5 months according to the cultivation season and stubble arrangement.

Fourthly, the growth cycle of rape.

If it is spring rape, the growth cycle is about 85- 130 days. If it is winter rape, the growth cycle is about 160-290 days.

1, germination stage: refers to the period from sowing to emergence, which is about 3-5 days if conditions are suitable (daily average temperature 16-20℃).

2. Seedling stage: it refers to the stage from seedling to bud, in which winter rape is about 120 days and spring rape is about 40-50 days.

3. Bolting period: refers to the period from budding to early flowering, in which winter rape lasts about 20-50 days and spring rape lasts about 15-25 days.

4. Flowering period: refers to the time from flowering to ending, which is about 25-30 days.

5. Pod maturity: refers to the period from flowering to harvest, which is about 25-30 days.

Five, the growth cycle of cucumber

Under natural conditions, the growth cycle of cucumber is about 90- 120 days.

1. Germination period: It takes about 5-8 days from sowing to the appearance of 1 true leaves.

2. Seedling stage: It takes about 30 days from the appearance of true leaves to the growth of 4-5 true leaves.
