Spring suitable for planting vegetables and fruits are:

1, cherry: fruit. Cherry is light-loving, temperature-loving, humidity-loving, fertilizer-loving fruit trees, suitable for growth in the average annual temperature of 10-12 ℃, annual precipitation of 600-700mm, annual sunshine hours of 2600-2800h or more climatic conditions. If there is frost damage in the area, the cherry orchard site can be chosen in the spring when the temperature rises slowly and the air circulates on the northwest slope.

2, melon: fruit. Early spring open field sowing should be stabilized above 15 ℃ to avoid rotting seeds. Plant growth temperature of 25-30 ℃ is appropriate, within 14-45 ℃ can grow. The flowering temperature is optimal at 25℃, and the fruit ripening temperature is 30℃. And the temperature difference between day and night temperature has a great impact on the quality of melon. The temperature difference between day and night is favorable to the accumulation of sugar and the improvement of fruit quality.

3, four season beans: vegetables. Specific spring sowing period: Northeast China in late April to mid-May; Northwest and most of North China in April, the northern plateau area in early May; East China in late March to early April; Central and Southwest China, most of the region in late February to early March; Yunnan in late January to early February; South China in December to the following April.

4, loofah: vegetables. Luffa like wet, afraid of drought, soil humidity is high, water content in more than 70% of good growth, less than 50% of slow growth, air humidity should not be less than 60%. 75% -85%, the growth rate is fast, more melons, a short period of time when the air humidity reaches the saturated, but still can grow and develop normally.

5, bitter melon: vegetables. Bitter melon is more vigorous, more lateral branches, longer reproductive period, there must be a good group structure, in order to seize the high yield. Therefore, the planting density (specifications) to be reasonable, the general planting spacing: equal spacing to 80 × 200 cm, wide and narrow spacing to 100 × (30 + 170) ÷ 2 cm is appropriate, mu planting 400-500 plants.
