Embodiment 1

[0047] This example provides a method for increasing crop yield and improving quality with hydrogen sulfide donor sodium sulfide. Sodium sulfide is used as a hydrogen sulfide gas donor to increase the yield and improve the quality of Sijiqing pakchoi. The seeds need to be grown at 22-25°C Germination treatment under temperature conditions, after the green leaves grow, hydroponic planting is carried out, starting from the two leaves and one heart, using the sodium sulfide solution with a concentration of 0-0.8mmol / L to treat the Sijiqing pakchoi for 2-4 consecutive times, Each interval is 12 to 24 hours, and then continue to use nutrient solution for 48 to 144 hours. This treatment is a cycle, and generally requires 4 to 6 cycles of continuous treatment.

[0048] Specific steps are as follows:

[0049] 1) Select plump seeds, rinse them with tap water 3 times to remove impurities contained in the seeds, disinfect them with 5% sodium hypochlorite aqueous solution for 10-15 minute...

Embodiment 2

[0060] This example provides a method for increasing crop yield and improving quality by using hydrogen sulfide donor sodium sulfide. The application of sodium sulfide as a hydrogen sulfide gas donor to increase the yield and improve quality of Suzhou green rapeseed, the specific implementation steps are the same as in Example 1.

[0061] In this case, Suzhou green rapeseed was used to conduct the experiment of hydrogen sulfide donor sodium sulfide to increase crop biomass and improve crop quality. The picked Suzhou green rapeseed was weighed with an electronic balance for its fresh weight, and samples were collected to determine the content of chlorophyll, protein and vitamin C. The experiment was repeated three times, and each time the content of chlorophyll, protein and vitamin C in the sample was determined for the leaves of Suzhou green rape at the same position. The results are shown in Table 2, and the results are represented by "mean ± standard deviation". The Duncan te...

Embodiment 3

[0066] This example provides a method for increasing crop yield and improving quality by using hydrogen sulfide donor sodium sulfide. The application of sodium sulfide as a hydrogen sulfide gas donor to increase the yield and improve quality of chicken feathers in four seasons. The specific implementation steps are the same as in Example 1.

[0067] In this example, four seasons chicken feathers were used to carry out the experiment of hydrogen sulfide donor sodium sulfide to increase crop biomass and improve quality. The fresh weight of four seasons chicken feathers after picking was weighed with an electronic balance, and samples were collected to determine the content of chlorophyll, protein and vitamin C. . The experiment was repeated three times, and each time the content of chlorophyll, protein, and vitamin C in the sample was determined as the leaves at the same position of the four-season chicken feather. The results are shown in Table 3, and the results are represente...

Abstract

The invention discloses a method for improving crop yield and quality using hydrogen-sulfide-donor sodium sulfide, and relates to a method for improving leaf vegetable crop yield and quality using sodium sulfide and a method for improving bean crop yield and quality using the sodium sulfide. According to different growing characteristics of different crops, the purpose of improving crop yield andquality is achieved by using different culturing manners and action manners. Sodium sulfide solutions with different concentrations are used for improving crop vital force, the photosynthesis of cropscan be enhanced by using external source sodium sulfide to improve chlorophyll content, and therefore the growing and developing of crops are promoted to increase the biomass of the crops. In addition, nutritious ingredients of products are analyzed by the method.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a method for increasing crop yield and quality by using hydrogen sulfide donor sodium sulfide. Background technique [0002] As an indispensable non-staple food in people's daily life, vegetables contain a variety of nutrients, such as carbohydrates, vitamins, cellulose and other nutrients, which are of great significance to guide a reasonable diet and improve people's health. With the rapid development of society and the change of lifestyle, people's dietary structure is also gradually changing. Vegetables, especially nutrient-rich leafy vegetables, are more and more popular among people. Leafy vegetables refer to vegetables that use the fat and tender leaves and petioles of plants as edible parts. Vegetables can be roughly divided into three categories: leafy vegetables, melons and eggplants, and rhizomes. Studies have shown that the nutrition of leafy veget...
