Embodiment 1

[0034] The present invention is realized in the following way: the water-soluble chemical fertilizer is mainly used, combined with the application of organic fertilizer, and the fertilization mode of the integration of water and fertilizer is adopted for the chemical fertilizer, and drip irrigation and fertilization are carried out in a small amount and multiple times.

[0035] Wherein the fertilization formula of each nutritional stage is: N:P in the branch growth fertilizer 2 o 5 :K 2 O=1:0.47:2.60~2.80; N:P in the flower-promoting fertilizer 2 o 5 :K 2 O:B=1:0.41:1.69~1.89:0.002; N:P in strong fruit fertilizer 2 o 5 :K 2 O=1:0.53:2.14~2.34; N:P in coloring fertilizer 2 o 5 :K 2 O:MgO=1:0.59:1.64 to 1.84:0.30. When the target output is 100kg, N0.83kg is needed, P 2 o 5 0.38kg,K 2 O 2.03kg. Using the method of the present invention can in time replenish the needs of the nutrients at each stage of dragon fruit growth, on the basis of satisfying the nutrients req...

specific Embodiment approach

[0036] The specific implementation method is as follows: Take the experiment at the dragon fruit base in Baoban Village, Dongfang City, Hainan Province in 2019 as an example.

[0037] Base fertilizer: annual commercial organic fertilizer 3000kg / mu, spread along the drip line of seedling stems, cover with soil and litter after fertilization.

[0038] Branch growth fertilizer: water-soluble fertilizer (120-90-120) 23.72-25.72ml, N: 6.16-6.36g, K 2 O: 17.01~17.21g, use the fertilization mode of water and fertilizer integration to carry out drip irrigation and fertilization several times, dilute the water-soluble fertilizer by 200 times each time, apply it once every 7-10 days, and use 2 liters / plant each time; the above N, K 2 O comes from the following raw materials: urea ammonium nitrate, potassium sulfate, etc.

[0039] Flower-promoting fertilizer: apply 0.78-0.98ml of water-soluble fertilizer (120-90-120) per plant during the bud stage. N: 1.40~1.60g; K 2 O: 0.80-1.00g; B...

Embodiment 2

[0050] Hainan Province is one of the most suitable cultivation areas for dragon fruit in my country and one of the areas with the most concentrated distribution. As the main species in Hainan, dragon fruit has high economic benefits, but there is no nutritional formula for dragon fruit stage. The invention discloses a kind that can The scientifically guided farmers' nutritional formula can supplement the nutrients needed for the critical period of dragon fruit nutrition in a timely manner, improve the growth of fruit trees, improve disease resistance, and then increase the yield and quality of dragon fruit. The results of the fertilizer effect test at the dragon fruit base at 18 degrees north latitude in Dongfang City, Hainan Province are as follows:

[0051] The complete development cycle of dragon fruit from bud to fruit in the local area is 38-42 days, the spacing between plants and rows is 0.35m*3m, the planting density is 9510 plants / ha, the variety is Dahong, and the plant...

Abstract

The invention discloses a pitaya nutrition formula. The nutrient formula comprises a branch growth fertilizer, a flower promoting fertilizer, a fruit swelling fertilizer and a coloring fertilizer. On the basis of the provided nutrition formula, the invention also provides a using method of the formula. The using method includes the steps of applying the branch growth fertilizer: applying 23.72-25.72 parts by volume of a water-soluble fertilizer, 6.16-6.36 parts by mass of N and 17.01-17.21 parts by mass of K2O to each pitaya plant; applying the flower promoting fertilizer: in a flower bud period, applying 0.78-0.98 part by volume of the water-soluble fertilizer, 1.40-1.60 parts by mass of N, 0.80-1.00 parts by mass of K2O, and 0.01-0.02 part by mass of B to each plant; applying the fruit swelling fertilizer: in a fruit expanding period, applying 3.19-3.39 parts by volume of the water-soluble fertilizer, 0.26-0.46 part by mass of P2O5, and 0.11-0.31 part by mass of K2O to each plant; and applying the coloring fertilizer: applying 3.13-3.33 parts by volume of the water-soluble fertilizer, 1.61-1.81 parts by mass of P2O5, 0.43-0.63 parts by mass of K2O, and 2.03-2.23 parts by mass of MgO to each plant in a fruit color changing period. According to the technical scheme, the yield and the quality of pitaya can be improved, and the utilization rate of the fertilizers is increased.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a dragon fruit nutritional formula and a method for using the formula. Background technique [0002] Pitaya belongs to the cactus family, and Liangtianchi belongs to the variety of Liangtianchi. It is native to Central and North America, and then spread to Vietnam, Thailand and other Southeast Asian countries and China's Hainan, Guangxi, Guangdong, Guizhou, Yunnan and other places. Now Vietnam is China ranks second in the country with the largest planting area of ​​dragon fruit in the world, with a planting area of ​​500,000 to 600,000 mu. Dragon fruit is not only delicious, but also has high nutritional value. It is rich in pulp fiber, vitamins and natural pigment anthocyanins. It has many mineral elements that promote human health and beauty, and is deeply loved by consumers. Hainan is located in the tropics and belongs to the tropical monsoon climate, with abundant rainfall through...
