Cucumber
Netherlands cucumber for female is more, mainly for greenhouse cultivation, unlike most outdoor cultivated varieties, they can not through pollination fertilization can finish the development of the fruit, but does not form a fully developed seeds.Early female system has the advantage of fruit maturity, high yield.The characteristics of this type of melon is: melon, one section one melon, section 1, 2 and more than 1 section melon melon.And, if appropriate management level, high yield potential is very big, 667 square meters of single crop yield can be over 10000 kg.1 year can be 2-3 times.

1, water plants to put rational release of aquatic plants can purify water quality, so that Dianchi water changes to reduce the frequency of 1 or 2 times a month, and can play a cooling sunstroke, reduce stress response, provide fish nest, pest control and other effects. Common water plants include water peanuts, water hyacinths, water lettuces, and fine green tea. In different seasons, it is necessary to use watercress proportionately and reasonably, summer water hyacinths and water lettuces are the main ones, spring and autumn are mainly water peanuts and fine arborvitae, and winter plants are not left to prevent freezing of yellow locusts. In general, plants are released 15 days before stocking. Before disinfecting, 0.01% potassium permanganate solution should be used to sterilize aquatic plants for half an hour. Aquatic planting area should not exceed 2/3 of the total pond area. At least 1/3 of the fish pond area must be vacated to set up the food table and facilitate the treatment of yellow peony. activity. In the daily management, remove excess aquatic plants or cut long water plants. In combination with Dianchi Lake, it will disperse 0.10.000001 quicklime on the grass to prevent aquatic fungal disease.
2, fish nest set a variety of tubes, bamboo, brick, waste tires, water grass, loofah, brown tablets, polyethylene mesh, etc. can be used for fish nest. In the production, the used bicycle tires are generally better treated by potassium permanganate solution after being sterilized. The tires are placed under the weeds, and 5 to 6 tires can be placed in each small tank. Bamboo can also be used, two bamboos in a row, each pool is set to 3 to 5 rows, each row spacing is about 0.3 meters. Each row of bamboo underlays the bricks, so that there is a larger space under the bamboo nest to facilitate the discharge of sewage. To fix the bamboo nest, it is best to press and put bricks on the top of the hole, which also plays a role in shading and concealing.
3. Summer shading Huang Xiaojing waterless soilless breeding pond is small (15-20 square meters), and the water level is shallow (15-20 centimeters). In summer, the water temperature can easily exceed 30 degrees Celsius, so it is necessary to shade the pool and shelter from the heat. . In general, shady nets are placed on the pool, and plants such as grapes, sponge gourds, and pumpkins are planted along the pool. But pay attention to the surface of the pool to leave 10% to 30% of light. When the temperature exceeds 30°C, it is necessary to deepen the water level in the pool, reduce the density of jaundice, and slowly inject new water (using groundwater to regulate the temperature of the fish pond).
4, water quality regulation
4.1 cross-disinfection water body every 10 to 15 days with lime 0.10.000001 or 10.000001 bleach Quanchiposa, cross-use. The northern part of the water quality is somewhat alkaline, and the number of bleaching powders used is less; the southerly water quality is somewhat acidic, and the use of quicklime may be more frequent.
4.2 Maintaining a suitable water level The yellow quail eats and breathes often needs to put its head out of the water. In order to reduce the consumption of body strength, the water level should be shallow. However, the water level is too shallow, the water temperature changes quickly, and the activity space of the Huangqi is small, which is not conducive to the growth and development of the Astragalus. Therefore, the general water level is 10 to 15 cm, and it can be increased to 25 cm when the temperature is high. If the grass grows luxuriantly, you can change the water once a month. Generally, you need to add fresh water according to the amount of water evaporation.
4.3 Maintaining Biodiversity In Dianchi Lake, field snails, small trash fish, and mud hoppers should be stocked to remove residual baits to adjust water quality. However, it should be noted that these organisms should maintain a reasonable proportional relationship in quantity. The stocking loach should be no more than 0.3 kg per square meter. The loach should be stocked after the tadpoles tame the compound feed, so as to fully utilize the loach to eat the feces of jaundice. Stocking crickets has special effects on preventing P. syringae peculiar plum spot disease. Generally, 1 to 2 can be placed in each small pond. The snails stored in a square meter pool should not exceed 0.25 kg. In addition, suitable amounts of green algae and the like can also be cultivated in the pond.
5. Ecological control of pests and diseases
5.1 Adjusting the water temperature The suitable temperature for the growth of Astragalus membranaceus is 15-28°C, and the optimal food intake temperature is 23-26°C. When the water temperature rises, the growth of low-temperature pathogens is inhibited, resulting in some diseases such as water mildew, white spot disease; pay attention to the temperature difference between water temperature should not exceed 10 °C, otherwise prone to print diseases. In addition, adjusting the water temperature to the optimal temperature will promote the intake of Astragalus and enhance its constitution.
5.2 Regulation Density Astragalus larvae stocking densities should be determined by the size of the pond, seedlings, feed and management level. Specifications generally in the end of each 15 to 20 grams is appropriate, stocking 80 to 150 per square meter, stocking density of 1.5 to 2 kg / square meter, generally should not exceed 3 kg / square meter, pay attention to timely sub-pool.
5.3 Prevention and treatment of Chinese herbal medicines The main approach to prevent and treat Chinese herbal medicines is to add comminuted Chinese herbal medicines or Chinese herbal preparations that have been crushed in compound feeds, or to use Chinese herbal liquids to splash water or soak fresh stems and leaves of Chinese herbal medicines in Dianchi Lake. At present, it has been confirmed that Chinese herbal medicine effective for Astragalus has purslane, rhubarb, astragalus, gallnut, tartary buckwheat tree, and Guanzhong and spicy sorghum.
5.4 Kill parasites The intestinal parasites of Astragalus membranaceus, especially the nematodes and capillary nematodes have a very high parasitic rate and parasitic intensity. This is also an important reason for the slow growth of Astragalus membranaceus and its decreased immunity. Therefore, the use of wild quail breeding to "treat the disease first," once the taming of the compound feed is successful, to immediately start killing parasites.
In addition, as with soil cultivation, the static waterless soilless culture should also pay attention to the scientific construction of ponds and timely alkalinization, strict screening of fish species, reasonable tame feed, strengthen the daily management of Dianchi.
About Huangshui Static Aquaculture Technology
In the wild, Astragalus inhabits shallow cemented soils because the soil can provide stable warm conditions and a dark living environment. In production, bamboo nests, bricks, and aquatic plants are used instead of soil to meet the living conditions of Astragalus and soilless culture. As far as soil cultivation is concerned, soilless astragalus cultivation has the advantages of low construction cost, convenient observation and management, easy feeding of compound feed, and prevention and control of diseases and insect pests. At present, soilless culture basically adopts aquaculture mode, but in places where water resources are in short supply, the mode of aquaculture without water is difficult to promote. The water-sew-free aquaculture in Huanghua is easier to promote than aquaculture without water. Silent water and soilless farming water-saving section labor, low investment, quick effect, wide range of adaptation, generally after 6 to 7 months of production cycle, can be increased by 3 to 5 times, net income per square meter Dianchi up to 100 ~ 150 yuan. The key technologies for aquaculture without water in Huangshui are briefly described below.
