When is the best month to plant virgin fruit? What kind of cultivation environment is needed?

1. Open-field cultivation:

1. Spring tomato: the seedlings were raised in hot wire plus small greenhouse in December, planted in the field after plastic film mulching in late March, and harvested from late May to late July. Select early-maturing and high-yielding varieties such as four Seasons Red and Saint Girl.

two。 Autumn tomato: sowing and raising seedlings in late June, the seedlings can be raised in a nutrition bowl, planted in late July, harvested before frost in late September, and four Seasons Red varieties can be selected.

2. Cultivation in protected areas:

1. Greenhouse mulching cultivation: in January, seedlings were covered by sunny beds or greenhouse hotlines plus small sheds, and planted in the first and middle of March. Plastic film mulching was best followed by planting. After planting, the shed was buckled and supplied to the market from May to July. It can be listed on the market about a month earlier than in the open field.

two。 Greenhouse cultivation: early December, cold bed or electric hotline seedling cultivation in the greenhouse, planting in late February, greenhouse covered with small shed, 4muri-early August harvest, selection of early-maturing, high-yield, high-quality varieties.

3. Rain-proof shed cultivation: similar to greenhouse cultivation, only the canopy is not exposed during the whole period, only the skirt curtain is removed, so that the canopy plays a rain-proof role in the plum rainy season and summer, and then covers the sunshade net on the canopy, which has a cooling effect and can prolong the supply period of tomatoes to August or even September. Varieties resistant to bacterial wilt can be selected.

4. Autumn delayed cultivation in greenhouse: sowing from late June to early July, planting at the end of August, and listing from 9mer to December. Covered with plastic film in October to keep warm, multiple mulching is feasible to extend the supply of fresh tomatoes to New Year's Day Festival.

5. Solar greenhouse cultivation: in areas with plenty of sunshine in winter, spring tomatoes can be cultivated in solar greenhouse, which can be put on the market in advance, generally raising seedlings in October, planting in November, and being on the market from February to late June.

The suitable temperature for the growth of virgin fruit is 24 ℃. It likes to be planted in the soil with strong light and deep soil layer. The cultivation of virgin fruit should choose loam which is rich in organic matter, deep plough layer, good structure, loose and breathable. When preparing the soil, the width of the border is 1.5 meters, the height of the ridge is 25 cm, and the width of the ridge is 40 cm. The border with a width of 1.5 meters can be planted in four rows, with a plant distance of 25m / m ~ 30cm and 8000 plants per mu. When planting, first trench in the border or half-high ridge, ditch depth of 15 cm, ditch, 250 kg of rotten dung per mu, additional phosphate fertilizer, 30 kg of superphosphate per mu. The virgin fruit is small in shape, large in quantity and vigorous in growth. pay attention to increase the number of fruit to make the fruit shape small and uniform, use double-stem pruning and cut off the rest of the lateral branches. In order to make the fruit with good coloring and high sugar content, more phosphate fertilizer should be applied.
