技术领域 technical field
本发明涉及无土栽培技术领域，具体涉及一种西瓜沙培营养液，适合于以河沙为基质的西瓜大棚种植。 The invention relates to the technical field of soilless cultivation, in particular to a watermelon sand cultivation nutrient solution, which is suitable for growing watermelons in greenhouses using river sand as a substrate.
背景技术 Background technique
果蔬的栽培量大，占用农地多，消耗人力物力资源较多，特别是在土壤贫脊地区，用沙为基质种植农作物（即沙培）可较好解决了这一问题。沙培是一种新型的无土栽培方式，果蔬定植于沙土上，通过安装滴管不断地向基质滴入营养液，为植物提供水分、养分、氧气，使植物能够正常生长并完成其整个生命周期，有别于传统土壤栽培形式下进行栽培，而且种植完一造农作物，河沙可以通过洗晒后重复利用。沙培营养液配方是沙培技术的核心，沙培营养液应均衡地含有植物生长所需的N、P、K、Ca、Mg、S、Fe、Mn、Cu、Zn、B、Mo等离子螯合态营养元素，具有缓释效应和缓冲性能，能有效提供水培植物生长所需养分，并可改善和防治水培植物缺素症状。 The amount of cultivation of fruits and vegetables is large, occupying a lot of farmland, and consuming a lot of manpower and material resources. Especially in areas with poor soil, planting crops with sand as a substrate (sand culture) can better solve this problem. Sand culture is a new type of soilless cultivation method. Fruits and vegetables are planted on the sandy soil, and the nutrient solution is continuously dripped into the substrate by installing a dropper to provide water, nutrients, and oxygen for the plants, so that the plants can grow normally and complete their entire life. The cycle is different from the cultivation under the traditional soil cultivation form, and after planting a crop, the river sand can be reused after washing. The sand culture nutrient solution formula is the core of the sand culture technology. The sand culture nutrient solution should contain N, P, K, Ca, Mg, S, Fe, Mn, Cu, Zn, B, Mo and other plasma chelates required for plant growth in a balanced manner. Synthetic nutrient elements have a slow-release effect and buffering properties, can effectively provide the nutrients needed for the growth of hydroponic plants, and can improve and prevent the symptoms of nutrient deficiency in hydroponic plants.
目前西瓜沙培使用的肥料多为尿素、复合肥、有机肥等，营养元素不能准确控制，需要根据植物生长情况多次进行追加，不方便管理。 At present, most of the fertilizers used in watermelon sand culture are urea, compound fertilizer, organic fertilizer, etc. The nutrient elements cannot be accurately controlled, and need to be added multiple times according to the growth of the plants, which is inconvenient to manage.
发明内容 Contents of the invention
为了解决现有技术中的上述问题，本发明提供了一种西瓜沙培营养液。 In order to solve the above-mentioned problems in the prior art, the invention provides a watermelon sand culture nutrient solution.
本发明提供的西瓜沙培营养液，溶剂为水，溶质包括硝酸钙、硝酸钾、磷酸二氢钾、硫酸镁、硝酸铵、硫酸钾、FeSO4·7H2O、EDTA-2Na、H3BO3、MnSO4·4H2O、CaSO4·5H2O、ZnSO4·7H2O和(NH4)6Mo7O24。 The watermelon sand cultivation nutrient solution provided by the present invention has a solvent of water and a solute comprising calcium nitrate, potassium nitrate, potassium dihydrogen phosphate, magnesium sulfate, ammonium nitrate, potassium sulfate, FeSO 4 7H 2 O, EDTA-2Na, H 3 BO 3. MnSO 4 ·4H 2 O, CaSO 4 ·5H 2 O, ZnSO 4 ·7H 2 O and (NH 4 ) 6 Mo 7 O 24 .
在生产过程中，通常将水培与沙培的配方通用，这容易造成沙培作物盐份中毒，影响作物生长。本配方是根据以河沙作为基质的无土栽培适合西瓜生长的营养液配方，经过多年生产实践和试验，对西瓜有很好的增产效果。本配方适合河沙为基质的无土栽培。 In the production process, the formulas of hydroponics and sand culture are usually used in common, which can easily cause salt poisoning of sand culture crops and affect the growth of crops. This formula is based on the nutrient solution formula suitable for watermelon growth in soilless culture with river sand as the substrate. After years of production practice and testing, it has a good effect on increasing watermelon production. This formula is suitable for soilless cultivation with river sand as the substrate.
作为一种优选方案，上述西瓜沙培营养液，每10立方米水中含有：硝酸钙0.95-2.95Kg，硝酸钾0.57-1.57Kg，磷酸二氢钾0.35-0.85Kg，硫酸镁0.47-1.97Kg，硝酸铵0.08-1.15Kg，硫酸钾0.04-0.15g；FeSO4·7H2O 23.80-26.80g，EDTA-2Na 32.80-34.80g，H3BO36.02-8.22g，MnSO4·4H2O 3.35-5.38g，CaSO4·5H2O 0.09-1.20g，ZnSO4·7H2O 0.20-0.65g，(NH4)6Mo7O24 0.02-0.06g。 As a preferred version, the above watermelon sand cultivation nutrient solution contains per 10 cubic meters of water: calcium nitrate 0.95-2.95Kg, potassium nitrate 0.57-1.57Kg, potassium dihydrogen phosphate 0.35-0.85Kg, magnesium sulfate 0.47-1.97Kg, Ammonium nitrate 0.08-1.15Kg, potassium sulfate 0.04-0.15g; FeSO 4 7H 2 O 23.80-26.80g, EDTA-2Na 32.80-34.80g, H 3 BO 3 6.02-8.22g, MnSO 4 4H 2 O 3.35- 5.38g, CaSO 4 ·5H 2 O 0.09-1.20g, ZnSO 4 ·7H 2 O 0.20-0.65g, (NH 4 ) 6 Mo 7 O 24 0.02-0.06g.
最佳地，上述西瓜沙培营养液，每10立方米水中含有：硝酸钙1.94Kg，硝酸钾0.97Kg，磷酸二氢钾0.69Kg，硫酸镁0.97Kg，硝酸铵0.14Kg，硫酸钾0.08g，FeSO4·7H2O 25.80g，EDTA-2Na 33.75g，H3BO3 7.12g，MnSO4·4H2O 4.36g，CaSO4·5H2O 0.18g，ZnSO4·7H2O 0.45g，(NH4)6Mo7O24 0.04g。 Optimally, the above watermelon sand cultivation nutrient solution contains per 10 cubic meters of water: 1.94Kg of calcium nitrate, 0.97Kg of potassium nitrate, 0.69Kg of potassium dihydrogen phosphate, 0.97Kg of magnesium sulfate, 0.14Kg of ammonium nitrate, 0.08g of potassium sulfate, FeSO 4 7H 2 O 25.80g, EDTA-2Na 33.75g, H 3 BO 3 7.12g, MnSO 4 4H 2 O 4.36g, CaSO 4 5H 2 O 0.18g, ZnSO 4 7H 2 O 0.45g, ( NH 4 ) 6 Mo 7 O 24 0.04 g.
目前沙培无土栽培营养液多数采用水培的配方，由于水培技术是通过水循环供应营养液，植物在水中营养吸收也比较均衡，营养液浓度较高，而沙培主要通过滴管输送供应营养液，植物吸收也较慢，养份一部分被植物吸收，一部分随水份流失，整个过程是个单向输送过程，如果按水培配方，不仅会因养分流失提高生产成本，而且容易造成盐份在河沙中累积，影响植物生长，甚至会造成盐分中毒而导致植物死亡。 At present, most of the nutrient solution for sand culture soilless cultivation adopts the formula of hydroponic cultivation. Since the hydroponic technology supplies the nutrient solution through water circulation, the nutrient absorption of plants in the water is also relatively balanced, and the concentration of the nutrient solution is relatively high, while the sand cultivation is mainly delivered through the dropper. The nutrient solution is also absorbed slowly by plants. Part of the nutrient is absorbed by the plant and part of it is lost with the water. The whole process is a one-way transport process. If the hydroponic formula is used, it will not only increase the production cost due to nutrient loss, but also easily cause salt. Accumulated in river sand, affecting plant growth, and even causing salt poisoning and causing plant death.
营养液的总盐浓度和酸碱度会影响营养液中养分存在的状态、转化和有效性。该配方无机盐类构成的总盐分浓度及酸碱反应均达到最符合西瓜生长需要的最佳值，以保证在植物吸收过程中造成的生理酸碱反应是比较平稳的，在无土栽培过程中较长时期内都保持其有效性。 The total salt concentration and pH of the nutrient solution will affect the state, transformation and availability of nutrients in the nutrient solution. The total salt concentration and acid-base reaction composed of inorganic salts in this formula have reached the optimal value that is most in line with the growth needs of watermelon, so as to ensure that the physiological acid-base reaction caused by the plant absorption process is relatively stable. In the process of soilless cultivation maintain its effectiveness over a long period of time.
与现有技术相比，本发明具有以下有益效果： Compared with the prior art, the present invention has the following beneficial effects:
本配方是根据以河沙作为基质的无土栽培适合西瓜生长的营养液配方，多年生产实践和试验证明，本配方对西瓜有很好的增产效果。一方面可促进西瓜生长，促进光合作用，提高高西瓜商品率，西瓜裂果率较低，瓜形大小均匀，并提高西瓜甜度；另一方面有较好的增产效果，以同样日本夏橙西瓜为例，在相同条件下中，用本配方营养液，亩产可提高40%以上。 This formula is based on the nutrient solution formula suitable for watermelon growth in soilless culture with river sand as the substrate. Years of production practice and tests have proved that this formula has a good effect on increasing watermelon production. On the one hand, it can promote the growth of watermelon, promote photosynthesis, increase the high commodity rate of watermelon, the rate of watermelon fruit cracking is low, the melon shape and size are uniform, and the sweetness of watermelon is improved; on the other hand, it has a better effect of increasing production. For example, under the same conditions, with the nutrient solution of this formula, the yield per mu can be increased by more than 40%.

对照例1：西瓜水培配方 Comparative example 1: watermelon hydroponic formula
购买生产常用的市售西瓜水培营养液作为对照例。 Commercially available watermelon hydroponic nutrient solution commonly used in production was purchased as a control example.
以上配方实例-31为实验组，对照例1为对照组，试验以日本礼品小西瓜（夏橙）品种为对象，每亩种植800株，每株留1个果。在相同栽培管理条件下，实施大棚沙培。结果如表1所示。 The above formula example-31 is the experimental group, and the control example 1 is the control group. The test takes the Japanese gift small watermelon (summer orange) variety as the object, planting 800 plants per mu, and leaving 1 fruit per plant. Under the same cultivation and management conditions, sand culture in greenhouses was implemented. The results are shown in Table 1.
表1 Table 1
实践表明，经过生产实践，用本配方水培的网纹西瓜果实大小形状均匀，网纹纹理清晰、匀称、美观，极少发生裂果现象，商品率较高，果肉清甜，产量明显提高40%以上。 Practice has shown that after production practice, the fruit size and shape of the reticulated watermelon cultivated with this formula are uniform, the reticulated texture is clear, well-proportioned and beautiful, the phenomenon of fruit cracking rarely occurs, the commodity rate is high, the pulp is sweet and clear, and the yield is significantly increased by 40%. above.
