Can the crops that can't be beaten by the two gossip, ginger and watermelon, can be interplanted? And the economic benefits are not bad. Let's take a look at the efficient cultivation techniques of ginger interplanting watermelon with Xiaobian! I. Economic benefits After years of ginger interplanting watermelon cultivation experiment, it is found that the average output value of 667 square meters is about 8,000 yuan, of which the ginger yield is 3200~4500 kilograms. In October, the market price is 1.60 yuan/kg output value 5100~7200 yuan. The output value before and after the Spring Festival will rise with the price. And the increase; watermelon production 3000~4000 kg, the listing price in mid-July is 0.60 yuan / kg output value 1800 ~ 2400 yuan. 2. Ginger interplanting watermelon planters The belt is 2.3 meters in 4 rows of ginger, with a line spacing of 50 cm, a width of 2 meters, and a gap of 30 cm. It is combined with ginger to form a mulched watermelon. Third, the ginger cultivation of watermelon cultivation points 1. Soil preparation and fertilization There is no land that has been planted with ginger in 3 years, and it has the characteristics of high terrain, convenient irrigation and drainage, and fertile soil. Before the New Year's Day, it is necessary to deepen the land. After a winter sun-dried and frozen, not only can some bacteria and underground pests be frozen, but also the soil layer can be deepened to improve the physical properties of the soil and improve the root growth environment. After the Spring Festival, the lunar calendar will be fine in March. Finely once, the ground should be leveled and the soil should be finely broken. When the land is prepared, 5000~6000 kg of high-quality soil fertilizer can be applied to the land of 667 square meters. The method of balanced fertilization is: the ratio of NPK to ginger is 3.5:1:4, the application of nitrogen is 21 kg per 667 square meters, the phosphorus is 6 kg, and the potassium is 24 kg. The base fertilizer is placed in the middle of two ginger species, each 667 The square meter is diammonium 13 kg, potassium chloride 40 kg, urea 23 kg, zinc sulfate 1 kg, borax 0.5 kg. When the valley is inverted before and after the fall, 10 kg of urea, 1 kg of zinc sulfate and 0.5 kg of borax are applied per 667 m2 in the ditch. In the middle of September, 10 kg of urea was applied per 667 square meters, and water was poured once every 2 days after fertilization to ensure that the fertilizer was not lost. The watermelon planted with 667 square meters needs 7-10 kg of nitrogen, 13 kg of phosphorus and 10 kg of potassium. The method of applying the base fertilizer is to apply strips or acupoints. The base fertilizer accounts for 60%~70% of the total fertilizer, and the top dressing should use points. Shi Zhan total fertilizer amount of 30% to 40%. 2, the choice of variety According to the local soil conditions, ginger roots such as Laiwu Dajiang, Taiwanese Feijiang, Linquan Lionhead, etc., which are free of pests and diseases, strong growth and thick stems, are selected. The watermelons are high-yield, high-quality, early-maturing varieties such as extra large red treasures. Very early Milong, Jingguanlong and so on. 3, the germination of the variety In the first ten days of April, the ginger is extracted from the ginger stalk. Generally, 350 to 450 kilograms of ginger are needed for every 667 square meters. It is necessary to choose a ginger that is full of fat, plump, and bright, and then go to the sick and grow ginger. 2 days of ginger, the highest yield of ginger with 50 ~ 75 grams of weight, sealed with double effect or grass ash to prevent the invasion of bacteria and germination after 2 days of drying. The germination can be placed in the corner of the kitchen or in the sunny place. It should be noted that 10 cm thick wheat straw should be placed around the ginger block, and then covered with a transparent film to keep warm. The suitable temperature for germination is 21~24 °C. If the temperature is low, the germination is slow; when the temperature is high, the bud length is weak and affects the yield. When the ginger bud grows to 0.5~2 cm long and 0.5~2 cm thick, it can be inserted. In mid-March, watermelons are bred in greenhouse nutrient mash. The germination temperature is 20~25°C, and transplanted on April 20th. After transplanting, mulching should be carried out to increase the ground temperature. 4, planting methods Ginger is planted in a ditch with a groove distance of 50 cm, a groove depth of 15 cm, and a plant spacing of about 15 cm. 7,000 to 9000 ginger can be planted per 667 square meters. Before sowing, sterilize with carbendazim solution for about 30 minutes. Water is poured through the bottom of the ditch and the ginger is placed flat on the bottom of the ditch, so that the seed buds are inclined upwards and placed in one direction. In the middle of the two gingers, leave the compound fertilizer mixed in advance, and cover the soil with 4~5 cm thick. Watermelon planting is first done with a ridge of 30 cm width. The watermelon seedlings are transplanted on a ridge with a plant spacing of about 40 cm. The mixed compound fertilizer points are applied to the middle of the two melon seedlings and covered with a mulch film. Conditional farmers can use a small bow shed. This will advance the growth period of watermelon and shorten the symbiotic period of watermelon and ginger. 5, chemical weeding 2 to 5 days after the ginger is planted with 200 kg of water and 50 kg of water per 667 square meters. After 1 month, the herbicidal effect is significantly more than 90%, or the use of herbicide ether, trifluralin, amphoteric phosphorus before seeding Spraying the ginger seedlings safely; the watermelon can be transplanted after spraying the herbicide. 6. Field management of watermelon During the seedling stage of watermelon, the ground temperature should be raised as much as possible to promote the early development of roots. Farmers need to protect the above-ground parts because it is very important to protect the leaves. In the case of plant growth in the case of leaving 1 melon per plant, generally do not leave the first female flower to sit on the melon, most of which is to choose the main female second female flower or the third female flower sitting melon. In the juvenile stage, one shape of melon can be selected and the remaining melons should be removed to ensure that the selected young melons grow rapidly. After transplanting the seedlings, watering or not watering should be done as little as possible. This can promote the formation of developed roots of the seedlings; as the plant grows, the water requirement of the watermelons will gradually increase, and the watermelons should control the water before flowering to prevent the madness. When the fruit is set, sufficient water supply should be ensured to facilitate fruit enlargement and increase weight. It is not advisable to water the water 7 to 10 days before harvesting, because this period is convenient for the fruit to accumulate sugar, so that good quality and large fruit can be obtained. Fourth, disease prevention and pest control The onset of ginger leaf blight is mainly concentrated in August. It can be sprayed 2:3 times with 1:1:150 times Bordeaux liquid before and during the onset of the disease. It can also be sprayed with carbendazim 800 times solution, and the anthracnose of watermelon, Fusarium also has a good control effect. The pathogen of ginger rickets is Pseudomonas spp., which has a rapid onset in the hot season and is difficult to control after the onset of the disease. At the time of onset, 40% of the sensation of ammonium is 160 times, and the root can be effectively sprayed with 40% of the sensitized ammonium 600 times solution, usually once every 7 days. Ginger is also known as the worm, and the heart spray is sprayed with 50% methamidophos or 90% trichlorfon 1000 times before the 3rd instar, and sprayed once in the insect for 10~15 days. The locusts and yellow stalks on the top have good control effects. Ginger is not resistant to cold and is not resistant to moisture. Therefore, ginger should be separated from each other, and watermelons can be selected from other similar crops. Zhuhai Mingke Electronics Technology Co., Ltd , https://www.mingke-tech.com
