Abstract

The features of the operation of the autonomous dual-slope trench-type solar greenhouse which is operating on alternative energy sources are briefly described in this article. The positive aspects of using the autonomous solar greenhouse with a small area of more than 1 acre are shown. A method for long-term high-quality storage of lemon crop grown in a solar greenhouse has been developed, as well as step-by-step steps for storing lemons in the mountainous conditions of Kashkadarya are given. It was determined that using the developed method, it is possible to store lemon crops for at least 8 months, and according to the results of many months of experiments, it was revealed that the weight loss of lemon from each box was up to 7% of the total mass. After analyzing the marketing of citrus fruits on the domestic market of Uzbekistan, we can say that when selling lemons in the summer season, the net profit will be about 35 million soums.

  7. The dynamics of price changes for 1 kg of lemon during its storage period is shown in
  8. Fig.5. The following equation was used in the graph to calculate the points using
  9. the least squares method. The fit confidence level is 0,97, which means that the curve fits the
  10. data very well. On the basis of Figure 5, we can conclude that if we sell the weight of the
  11. lemon crop in July, then the net profit will be about 35 million soums.
  13. CONCLUSION. Most consumers know that picked lemons become dry and unusable for
  14. using after a week. Several methods exist to keep them fresh and juicy. In spite of this, most
  15. of these methods require huge amounts of energy and regular maintenance of personnel. The
  16. simplest method of high-quality storage of citrus fruits is considered to store them in the
  17. sealed condition and in large-capacity refrigerators. The disadvantage of this method of
  18. storing lemons is considered the high consumption of electricity to ensure a stable
  19. temperature and humidity climate and the need for their quick consumption after removal
  20. from the refrigerator.
  21. As the results showed, it is possible to ensure high-quality storage of lemons without
  22. unnecessary energy costs using the method proposed by us. But only partially maintenance of
  23. personnel is required before sending them to the consumer. Analyzing Fig. 5, we can conclude
  24. that 3-4 years after planting the seedlings of lemon, the seedlings will be ready for a full
  25. harvest. In addition, in the period until the full harvest of the lemon, greens (dill, radish, bell
  26. pepper, eggplant) and potatoes, radish, turnips can be grown around lemon seedlings. It has
  27. been established that the autonomous trench-type solar greenhouse for small-scale farms
  28. with an area of 105 m 2 (~ 1.1 acres) pays for itself in the fifth year of operation, taking into
  29. account the growth of lemon seedlings.
