For cultivation of strawberry recommend to choose greenhouses from polycarbonate. Unlike film and glass designs, they keep heat better that helps to support optimum temperature condition.
Preparation of the soil and planting stock
For landing of strawberry in the greenhouse it is desirable to use the soil which has remained after cultivation of various cereal cultures. Soil on which cabbage and potatoes grew is not suitable for this plant. It is possible to take mix of the cespitose earth and sawdust. It is necessary to bring manure, compost, peat and complex mineral fertilizers in it.
As planting stock it is the best of all to choose the strawberry mustache received from maternal plants which were grown up in the open ground. Future saplings cut off from bushes during weeding, the most qualitative of them at first land on the temporary place, and at the end of October transfer to the greenhouse.
Humidity, temperature and light
Strawberry can yield harvest in winter time only at observance of special light conditions therefore it is very important to create the system of illumination. In cold season, kidneys can be stuffed up, for development of peduncles and the correct blossoming of plants it is necessary to extend daylight hours till 15-17 o'clock in day. If you want to receive big harvest of strawberry in the winter, it is necessary to get the system of automatic heating and watering. The number of fruit kidneys will increase if to increase temperature gradually. At first it is desirable to support it at the level of +25 °C that seedling has begun to take additional root. In process of rooting of bush temperature is lowered to +15 °C. Within several weeks after landing the humidity of 80-85% is necessary, then it is recommended to lower to 75%, during blossoming it should not exceed 70%.
Leaving and pollination
Strawberry needs to be watered in due time evenly by means of the special systems of drop irrigation. The first 3-4 weeks carry out abundant drop watering daily when bushes take roots — every 5-8 days. In order that moisture remained in the soil, do mulching. Plants feed up time in 13-15 days solution of potash salt and superphosphate. To prevent strawberry diseases, it is regularly necessary to air the greenhouse for the purpose of lowering of humidity. Wind, abundant precipitation or insects is necessary for pollination. Creation of artificial wind by means of fans - the simplest method which efficiency reaches 90%. During blossoming of bushes they are included at several o'clock a day. If on the street heat and wind of average force, it is possible to create draft in the greenhouse. For this purpose on the opposite sides of construction open two windows.
