Ginger grows fastest in summer and autumn, and has the greatest impact on yield composition. It is also the most severely affected by pests and diseases. In particular, ginger acaridism causes plants to die and ginger rots, resulting in reduced yields. Therefore, it is necessary to strengthen the summer and autumn management of ginger and ensure the normal growth of ginger in order to obtain high yields. Specific management and technical measures are as follows:
First, cover the surface. In summer and autumn, 2-3 tons of cultivars shall be planted around the plants with rotted waste fertilizer, pond mud, fire-burning soil or other soil fertilizers, and then covered with dried straw or other weeds. The grass is 5-6 cm thick to cover bare ginger, keeping the soil moist and promoting the development of ginger.
Second, timely fertilization. In the summer and autumn, it is necessary to apply a NPK fertilizer once a month at the roots, 50-60 grams of NPK fertilizer per plant per time, and dilute with water. At the same time, every 100 days of spraying of leaves with a vegetable-specific active organic fertilizer solution of 800 mg of organic humic acid should be sprayed. It is advisable to spray wet leaves with drip.
Third, shading sunscreen. Jiang Xi's cool environment, avoid direct light, in the summer and autumn when the sun is strong, it must cover the transmittance of only about 50% shady net, or take a high shed about 1 meter, covered with foliage, To prevent direct light and maintain ventilation, create a cool environment for ginger growth.
Fourth, control pests. In summer and autumn, it is necessary to administer 600 times of enemy pine 1500 times Shennongsu chelating fertilizer mixture every month, every time, every plant is 3-5 kg ​​or so to prevent ginger rickets. At the same time, it is necessary to spray once every 15-20 days Lobsburn 1000 times, 800 times the thiophanate-methyl mixture, or 1,000 times the farmland music, 800 times the Lei Da Mier mixture, spray the wet leaves to begin with water droplets It is advisable to drip down to prevent other pests.
Fifth, pay attention to drainage. Ginger afraid of picking stains, soil moisture, water accumulation, will cause the roots to die. Therefore, in the summer and autumn, we must pay attention to doing a good job of drainage work. After the heavy rain, we must promptly eliminate the stagnant water in the ginger garden to prevent accumulation of water.
