Abstract

The invention discloses a one-time fertilization planting method for pineapples, which comprises the following steps: digging a shallow trench in the pineapple planting field, applying a first layer of fertilizer in the trench, backfilling soil for the first time, applying a second layer of fertilizer on the backfilled soil, backfilling the soil for the second time, covering a mulching film on the backfilled soil for the second time, and planting pineapples. The method scheme can effectively reduce the fertilizing times and fertilizing amount during pineapple planting, and only needs to fertilize once from pineapple planting to fruit bearing. In addition, the fertilizing method is simple and convenient to operate and can be popularized and used on a large scale.

Description

One-time fertilizing and planting method for pineapples

Field of the method

The invention relates to the field of agricultural planting, in particular to a planting method for applying fertilizer to pineapples at one time.

Background method

Pineapple (Ananascomosus (L)) Merr. ] is also called pineapple, belongs to pineapple herbaceous fruit trees of the genus Ananadis of the family Ananadiaceae, is a famous tropical fruit, the growth period of the pineapple is long, the whole growth period from seedling planting to fruit harvesting is as long as one and a half years, 3000 plants or even more are planted per mu of pineapple planting, the biomass is large, and the nutrition absorption is large.

Therefore, exploring a pineapple planting method capable of effectively reducing the fertilizing amount and the fertilizing times will greatly reduce the manpower and material resource input of fruit growers, promote the income increase of the fruit growers, and also has important significance for promoting the sustainable development of the pineapple industry in China.

Disclosure of Invention

The invention aims to disclose a one-time fertilization planting method for pineapples.

The method scheme adopted by the invention is as follows:

the one-time fertilization planting method of the pineapples comprises the following steps: digging a shallow trench in the pineapple planting field, applying a first layer of fertilizer in the trench, backfilling soil for the first time, applying a second layer of fertilizer on the backfilled soil, backfilling the soil for the second time, covering a mulching film on the backfilled soil for the second time, and planting pineapples.

Preferably, the width of the shallow trench is 55-65 cm, the depth is 25-35 cm, and the interval between trenches is 55-65 cm.

Preferably, the first layer of fertilizer applied is pineapple stem leaves.

Preferably, the application amount of the first layer of fertilizer is 4000-5000 jin per mu.

Preferably, the soil is backfilled for the first time to be level with the ground.

Preferably, the applied second layer of fertilizer consists of decomposed organic fertilizer, compound fertilizer and phosphate fertilizer.

Preferably, the decomposed organic fertilizer is chicken manure or peanut bran.

Preferably, the soil is backfilled a second time to 15 centimeters above the ground.

Preferably, the applied amount of the second layer of fertilizer is 1500 jin of chicken manure or 750 jin of peanut bran, 150 jin of compound fertilizer and 200 jin of phosphate fertilizer applied to each mu.

Preferably, the pineapple is planted with a depth of 5-8 cm.

The invention has the beneficial effects that: the method scheme can effectively reduce the fertilizing times and fertilizing amount during pineapple planting, and only needs to fertilize once from pineapple planting to fruit bearing. In addition, the fertilizing method is simple and convenient to operate and can be popularized and used on a large scale.

Detailed Description

Pineapple is planted according to the following steps

1. And excavating planting ditches, namely excavating the pineapple planting field into shallow ditches with the width of 55-65 cm and the depth of 25-35 cm, wherein the intervals between the ditches are 55-65 cm.

2. And (3) applying the stem leaves of the pineapples to the ditch, and applying 4000-5000 jin of the stem leaves of the pineapples to each mu of the ditch (shown in figure 1).

3. And backfilling soil, namely backfilling a layer of soil on the miscellaneous fertilizers to ensure that the soil layer is just level with the ground.

4. Applying a mixture of decomposed organic fertilizer, compound fertilizer and phosphate fertilizer, and applying the decomposed organic fertilizer (1500 jin of chicken manure or 750 jin of peanut bran) on the soil, 150 jin of compound fertilizer and 200 jin of phosphate fertilizer.

5. And backfilling soil, and fertilizing the backfilled soil to enable the soil layer to be higher than the ridge surface 15 cm higher than the ground.

6. And covering a mulching film, covering the whole ridge surface with a black and white mulching film, and compacting the periphery of the mulching film by soil so as to prevent the mulching film from being blown down by wind.

7. And (2) planting pineapple seedlings, selecting pineapple bud-sucking seedlings with the depth of more than 35 cm, soaking the bases of the pineapple seedlings with liquid medicine of 500 times of phoxim and 500 times of carbendazim for 8-10 minutes before planting, planting after the pineapple seedlings are dried in the air, planting in double rows, planting 3000 plants per mu, and burying to the depth of 5-8 cm (shown in figure 2).

8. And (3) growing and flower forcing, wherein flower forcing can be started after 10 months of growth of the pineapple plants, and the flower forcing method is consistent with the traditional planting method.

The one-time fertilization of the invention is compared with the growth and yield of the traditional fertilization plants, and the effect is shown in the following table:
