The jujube tree and the eagle pepper create a favorable microclimate for both sides of the field, reducing the occurrence of pests and diseases. Tianyingjiao is an excellent dry pepper variety of clustered pepper, which is resistant to disease and high yield. It prefers warm and moist environmental conditions and is afraid of strong light and heat. Summer jujube tree has a certain shade effect on Tianyingjiao, so that the light intensity of Tianyingjiao plant is weakened and the temperature is reduced, which is beneficial to the growth and development of Tianyingjiao. The narrow distribution range of the root system of the pepper root is vertically distributed at about 15 cm, horizontally at 25 to 30 cm, and the stems are erect, the plant shape is compact, and the height is about 50 cm. It is suitable for intercropping of jujube trees. In addition, due to the covering effect of the green leaves of Tianyingjiao plant, soil moisture evaporation was effectively inhibited during the hot summer, and the soil moisture content was increased, which was beneficial to the growth and development of jujube trees. Before February 20th, he chose to make a sunny lee, and the terrain was relatively high. He had not planted solanaceous crops, and had a water source and a convenient place to manage. Yangshuo runs east and west, with a depth of 30mm, a width of 1.5 to 2.0m, and a length depending on the seedling volume, and is built around 10 to 15mm in height. After the impotence is done, fill in the nursery soil, and pour enough water to make sure it is enough. 2 to 3 days after sowing before fully sowing, soaking in cool water (55°C) for 6 to 8 hours, soaking and drying, packing in wet gauze, putting in pots, germination at 20°C～25°C . During the germination, wash with water once a day, until most of the seeds are exposed to white tips. In early March, select fine weather for sowing. The amount of 125g per square meter, spread evenly, after sowing cover 0.5 ~ 1.0mm thick screened fine soil, cover film. Four-leaf and one-for-one watering are strictly prohibited, and measures to cover soil and protect the earth should be taken. If the seedbed is too dry, use a spray bottle to spray water. After the leaf surface water evaporates, sprinkle a thin layer of fine soil. SUNSON`s Baking Business Division focuses on solutions for flour and flour

Jujube trees were planted in a north-south direction with a spacing of 3m and a row spacing of 7m. Jujube tree nutrient zones were set aside between the internodes of Tianyingjiao with a spacing of 20cm and a row spacing of 30cm.
After the fall of the fallen leaves, the plants are planted before the sprouting in the coming spring and the holes of 80 to 100 cm are dug from the location of the rows. When digging, do not mix the topsoil and the soil and soil. The soil is mixed with the appropriate amount of organic fertilizer, and then backfilled. The backfill is only 10-15cm away from the ground level. Then, water the soil to sink the soil until all the soil in the pit has penetrated and then planted. When planting, put the treated seedlings into the pits, first bury the remaining topsoil around the roots, and then use the remaining soil to bury the seedlings well. The depth requirement for the buried seedlings is slightly deeper than that of the original seedlings. 1cm. It's not good to go too deep or too shallow. After planting, lay the tree plate and pour water.
After the planting, the date of the soil in the jujube garden was checked in a timely manner, and water shortage was found. Immediate replenishment was required to maintain the soil relative water content of 60 to 70%. When the branches grow to 30cm, one can use nitrogen fertilizer-based quick-acting fertilizer once, 30 grams per plant is appropriate, not large; the second and third years before the germination combined with the water of the eagle pepper planting organic Fertilizer combined with watering topdressing urea in July and August, 0.2~0.3kg per plant; After the third year, the normal result tree management will be used to fertilize the whole year mainly with organic fertilizer, supplemented by chemical fertilizer, the nutrients provided by organic fertilizer can not be lower than 60%. In general, pure nitrogen 2Kg, pure phosphorus (P2O5) 1.2Kg, and pure potassium (K2O) 1.6Kg are used for producing 100Kg fresh dates. Each tree with a yield of about 35Kg applied 35 to 50kg of quality fertilized farmyard fertilizer (kg pound fruit or half kilogram of pound fruit), diammonium 1.5Kg, and urea 0.5Kg, applied in the form of base fertilizer, accounting for the annual fertilization amount. 70%. The amount of top dressing depends on the application of basal fertilizer. In general, diammonium 0.7Kg is applied before flowering of each tree; diammonium 0.5 to 0.7Kg and potassium sulfate 0.5Kg are applied during young fruit; and diammonium 0.5Kg is applied during fruit enlargement. , potassium sulfate 0.75Kg.
Precipitating water before and after mid-April, irrigation water supplement by irrigation, is conducive to the occurrence and growth of roots, can promote the jujube tree, jujube hanging and jujube head growth, bud differentiation. In late May, it entered the early flowering period and entered the flowering period in early June. During the drought season, it takes a lot of water for flowering and fruit setting. Watering at the initial flowering stage can increase the soil and air humidity, which is conducive to pollen germination, completing the fertilization process and increasing the amount of fruit set. In early July, the jujube tree is in the stage of rapid growth of young fruit, which requires a large amount of water. In some years, the rainy season has not yet arrived, and the soil is relatively dry. It is necessary to timely supplement the soil moisture through irrigation. Otherwise, the fruit growth is inhibited.
The first 1 to 2 years after planting and survival are generally not pruned, when the trunk is about 1 meter from the ground, and the diameter is about 1.5 to 2.0 mm, dry shaping is performed, and the drying time is fixed at a height of 70 to 120 mm before germination in the spring. The results can be opened in the fourth year and later trimmed according to the normal result tree.
Sowing seedlings in early March. Every 10 to 12 m2 of Yangshuo needs 1.5m3 of nursery soil, and 10~15mm thick. The nursery soil was made of 200 kg of high-quality farmyard fertilizer, 1.0 kg of urea, 2.0 kg of superphosphate, 0.5 kg of potassium dihydrogen phosphate, 150 mg of carbendazim, and 150 g of carbendazim, and a small amount of sifting fine soil. At the same time, some pesticides for controlling underground pests were added.
After sowing, cover the film, cover the grasshopper at night, and keep the temperature of 10mm above 20°C to facilitate seedling emergence and no release before emergence. Qi Miao to the two leaves before the attention of insulation, during the day 20 ~ 25 °C, maintained at around 17 °C at night. When the seedlings grow to two leaves and one heart, they begin to let out winds. Shed temperature is maintained at 20-22°C during the day and 15-17°C at night.
When the seedlings grow to two-leaf and one-leaf, the seedlings should be planted in a dense seedbed, and the seedlings should be weak and strong, and the seedlings should be kept at a distance of about 5 cm.
10 to 15 days before planting, generally in late April, select the cool weather to remove the film and carry out the hardening of the seedlings to adapt to the exposed natural environment.
In the first half of May, fine weather was selected for planting. Covering with plastic film, the film width is 1.4m, thickness is 0.005mm, membrane width is 120mm, planted in four rows, then watering seedlings are poured immediately after planting.
Field management
When the main stem of the plant is 14 to 16 leaves, the buds at the top are removed in time. After topping, apply 15~20Kg urea per acre and water to promote lateral branch growth. Apply 20 to 25 kg of diammonium phosphate per acre at the beginning of flowering. Into the mid-August, do not topdressing nitrogen fertilizer to prevent greed. In case of flooding in time. Watering is controlled from mid-September.
