tea garden
(a) cover the grass. The grass is planted on both sides of the tea tree. The grass source is mainly straw and there is better grass coverage. Grass thickness 8 cm to 10 cm.
(b) Appropriate fertilization. Especially in young tea gardens, fertilizers are best used for the application of biogas liquids, and 0.5% urea or 0.5% potassium dihydrogen phosphate aqueous solution can also be used for extra-root fertilizer.
(3) Picking in time to reduce the water consumption of shoots and pay attention to keeping the leaves and trees.
(D) Tea farms planned to be cut in spring should be put on hold until the drought is completely relieved and the spring tea is cut after the end.
(5) Tea garden irrigation: Tea gardens with original irrigation conditions can be irrigated and drought-fighted. The irrigation volume should be determined according to the weather conditions and the tea tree water requirement. Tea gardens without irrigation facilities should organize deployment equipment and actively use state agricultural machinery subsidies to purchase tea garden irrigation equipment.
(6) Shallow plough weeding. Timely weeding can reduce surface water evaporation. Avoid deep plowing in tea gardens during dry seasons, so as not to cause tea trees (especially young) to suffer sudden water loss and death due to root injury.
sugar cane
(a) Select improved varieties. The use of Taiwan Youyu, Xintai sugar 25 and other drought-resistant high yield varieties.
(b) Mechanical deep plowing and deep loosening. Deep plowing of 35 cm to 45 cm deep with high-powered tractors can increase the amount of water stored after the rain and the moisture does not easily evaporate. Deep-groove flat-bottom planting is adopted, and the soil for soil preparation must be finely crushed in order to enhance the water retention capacity of the soil and facilitate the growth of the roots of the cane and the germination of the shoots.
(c) The following water conservation techniques. 1. Add organic fertilizer. 2. Use fresh stems or shoots of various stems, soaking and disinfecting, and appropriate watering after seeding. 3. The use of cane tip (tail) stripping leaves (sheaths) does not cut down the seeding technique. 4. Newly planted sugarcane under the planting ditch and covering the cane.
(D) Comprehensive drought prevention measures: 1. "Three wet" (seedling wet, wet fertilizer, planting ditch wet) under the seed, after the rain cultivating loose soil, sealed ditch storage. 2. Use autumn and winter planting to manage fertilization in advance and seal it early to prevent surface water loss. 3. Covered with plastic film or sugarcane leaf. 4. Expand the application area of ​​sugar cane technology for spraying alcohol waste. 5. Rational interplanting. 6. The lack of severe seedlings can be used to reduce the size of the plants.
Edible fungi
At present, the main varieties of mushroom cultivation are Agaricus bisporus, Pleurotus ostreatus, shiitake mushrooms, edible fungus, Flammulina velutipes, and so on. The production water requirement is not large, but the extremely high temperature of drought may affect the production of edible fungi.
(a) Pay attention to site selection for production sites. The site should be located as close to the water source as possible, and good water diversion and sprinkler irrigation facilities should be constructed to accumulate rainwater and spring water. Daily cultivation should save water and spray and drip irrigation should be adopted. Mushroom construction should be conducive to heat preservation and moisturizing.
(b) Scientific vaccination. Inoculation of acupuncture points deepens the filling of bacteria, which is conducive to enhancing drought resistance and reducing the external temperature difference to the stimulation of the bottom seed species of seed holes. The survival rate is improved.
(3) Distributing and moving piles in due course. Transfer the fungus rods from places with higher temperatures to downstairs, mud rooms and well-ventilated rooms. Pay attention to stacking and stacking in triangles or wells to reduce the number of layers of bacteria sticks and maintain indoor ventilation. It is best to carry out piles and piles in the evening.
(D) shade, ventilation. Every night from 8 pm to 7 pm, the room is forced to ventilate, try to keep the room temperature below 33°C, avoid room temperature above 33°C for more than 2 hours to 3 hours, and control the relative air humidity. 70% or so.
(e) Correct handling of rotten bars. Found that there are rotten rods, bacteria infected immediately pick out concentrated, do not arbitrarily discard, so as not to infect each other and pollute the environment.
(vi) Reuse of culture materials. Rotten rods, which are also better in the texture of culture materials, can be exposed to sunlight and reused to produce mushrooms, coprinus comatus or other high-temperature varieties.
potato
Potatoes affected by prolonged dry weather may cause shortening of the growth period, lack of photosynthetic capacity of plants, affect tuber formation and enlargement, increase the production of bad potatoes, and decrease yield and quality.
(1) Through measures such as pumping wells, pumping water from rivers, etc., make use of all available water sources, promptly irrigate and keep the root soil moist.
(b) Adopt water-saving irrigation technologies such as sprinkler irrigation, wet irrigation and drip irrigation.
(3) When ditching irrigation, only half ditch water can be irrigated, and flooding can not be flooded. Drain and drain water in time to avoid affecting the normal growth of roots and mashing of the mash.
