Ginger is an important export vegetable in China. However, due to the traditional management habits of ginger farmers, and repeated repetition, the quality of ginger has deteriorated and the yield has been reduced. In some places, Jiangyan disease is prevalent. We have explored a set of high-yielding, high-yield, high-yielding cultivation techniques for ginger on the basis of several consecutive years of trials, which also has a certain control effect against ginger borer. Here are just some of the major aspects of the introduction. First, use a shading net with a light transmittance of 40% instead of traditional ginger shade grass as a positive shade-tolerant plant, not intolerant to strong light and high temperature, if the lack of light will also affect its normal growth, the traditional cultivation methods are to come in Shaded. That is, after sowing ginger seed, in the south side or west side of ginger ditch, insert the corn grass or corn stalk, etc., and alternately insert obliquely at a distance of 10-15 cm, 70-80 cm high, so that the ginger ditch is in a shade state. The biggest disadvantage of this shading method is uneven shade in time and space. At the hottest time in July and August, the shading area is the smallest, and the shading rate is far from enough. The shade material we use is a shade net with a light transmittance of 40%. Before the ginger is planted, the wooden piles are laid according to the structure of a simple and large shed of vegetables. The highest point is about 2 meters in the middle, and the two sides are slightly shorter. Sew several shade nets together by ground width, preferably 4-5. After the ginger is sown, the shade net is fixed on the stake. This shading measure is easy to operate, and it is also very convenient for late-stage ginger fields such as fertilization, spraying, weeding and earth-cultivation. Pay attention to the withdrawal time should be 5-10 days ahead of the time of traditional shadow grass, because the group of ginger fields under the shading net is more prosperous. After the temperature drops in the late period, the ginger grows faster and faster on the ground and underground, preventing the leggy on the ground. The use of shade nets can increase production by more than 50%. Second, the late harvest of ginger growth in the traditional harvest time a few days before the frost. In fact, the growth of ginger is still very strong at this time, mainly due to the return of nutrients and the enrichment of the contents of ginger. At this time, on the wooden stakes that had fixed the sunshade net, a few bamboo sticks were placed on the side, and then a large shed was buckled. This avoided the sudden frost problem. After delaying the growth for 20 days and then picking a good harvest, it can increase the output by more than 17% on the basis of the shading net. Third, the use of virus-free ginger to replace the traditional type of self-retained ginger virus-free vegetables due to the huge advantages in yield and quality more and more people's attention, through the cultivation test found that detoxification ginger than normal ginger yield more than 30%, and resistance Ginger disease has a significant effect. Fourth, the use of shade nets need to pay attention to the following points 1, shade net transmittance of 40% is appropriate, too large, shading effect is poor; too shady too strong, easy to grow. 2. The shade net erection height should not be less than 1.5 meters in order to facilitate the ventilation under the net. 3. Due to the shade net, the microclimate is better, the temperature and humidity are suitable, and certain diseases (such as Jiangyan) are prone to occur, and attention should be paid to prevention. 4. The time for withdrawing the sunshade net should be 5-10 days ahead of the time for pulling ginger shaver in order to prevent the ginger from gaining longevity. 5. It is not advisable to detain the arch shed too early, and it is easy to produce high temperatures prematurely and it is too late to be susceptible to frost. After noon, pay attention to the wind. 6, 3-5 days before deducting a large shed should be poured water again, after the shed should not be watered, to prevent excessive humidity inside the shed, affecting the quality of ginger. 7, detoxification ginger individual growth than normal ginger Wang, to prevent the group is too large, it is appropriate to adjust the density, the general density of ginger cultivation can be 50 cm 20 cm, virus-free ginger cultivation density can be 55 cm 25 cm.
