High-yield field management techniques and key points of loofah

Many crops want to achieve high yields, they cannot do without field management, because in this field management stage, there are many measures that need to be implemented. Let’s learn about the high-yield field management techniques of loofah and see where you are not in place. .

High-yield field management techniques and key points of loofah

1. Base fertilizer

The basal fertilizer is applied in the basal manure ditch, and applied in strips, first applying pile manure, then mixing chemical fertilizers and applying it on the pile manure, then making a small bed and covering it with silver-black plastic cloth. Top dressing should be applied once every 3 weeks as the principle. Before top dressing, the furrow should be irrigated first. After the water has penetrated into the border, the top dressing should be applied on both sides of the border and the bottom of the border.

2. Ground preparation

When the soil is semi-dry and wet, plow the open and shallow basal fertilizer ditch on the planting row according to the row spacing. After the basal fertilizer is applied, the basal fertilizer is small, and then the silver black plastic cloth is covered on the small basal surface, such as with a machine Operation, the small work frame and the plastic cover can be completed at one time, so that the two sides of the plastic sheet are buried in the two sides of the small work frame to avoid being blown away by the wind. Later, with the growth of the loofah, the soil will be cultivated again to complete the wide and high border style. Before loofah cultivation, planting holes are drilled on the plastic sheet according to the plant spacing, and one plant is planted in each hole, and then watered after planting. It should be sparsely planted during the high temperature period and denser during the low temperature period.

3. Sowing period

Luffa can be planted and cultivated annually, but it is most suitable for planting from December to August. When sowing later in various places after September, although the earlier the occurrence of female flowers, the more often, but the later stage of growth gradually enters the low temperature period, the growth is weaker, the disease is more severe, and the senescence is easy.

4. Sowing seedlings

The husk of the loofah seeds is hard, especially the angular loofah, so it is advisable to pre-germinate sowing, that is, take out the seeds after soaking the seeds for 2 hours, then roll the umbilical mound of the seeds apart, and place them in the dark at 25-300C to accelerate the germination. When the seed husk comes out, it is sown in a plug tray with medium, the seeds are laid flat, and the bud tip is downward as the principle. The sowing depth is about 1.5 cm. When the three leaves are spread, they are planted in the field. During the nursery period, the high temperature period is about 11-14 days, and the low temperature period is about 15-18 days. When the short-day varieties are cultivated during the long-day period, after the cotyledons are unfolded, shading and short-day treatments are performed to promote the occurrence of female flowers.

5. Horizontal trellis cultivation

The shed surface is about 1.5 meters away from the surface, and the border is 5-6 meters wide. It is a high border, one border is planted in two rows, and the loofah is planted on the border of the border and the spacing is 0.4-0.5 meters. This method can also be cultivated using grape racks. When the loofah is first planted, the borders can still be intercropped with other short-term crops. If horizontal trellis cultivation is invaded by a hurricane, the wind surface is large and it is easy to be blown down by the wind. Therefore, autumn and winter are the principle, such as spring and summer, not close planting, slightly sparse planting, and moderately remove some stems and leaves. To reduce wind resistance.

6. Fertilizer and fertilization

The type and amount of fertilizer and fertilization method of loofah can refer to bitter gourd or flat cat in principle, that is, loofah has strong fertility absorption, long growth and fruiting period, growth and fruiting at the same time, and strong fruiting force, so it is recommended to continue fertilizing after fruiting In order to maintain the continuous growth of the stems and leaves, the fruit will continue to grow and the yield will increase. Especially after continuous rainfall, some of the nutrients in the soil have been lost with the rain, so topdressing should be applied after the rain.

7. Irrigation and drainage

The loofah has long stems and large leaves, and the amount of water evaporation is large. Therefore, it is advisable to pay attention to irrigation and keep it moist. Irrigation should be irrigated by furrows. Pay attention to drainage when it rains, so that the roots are not soaked in water, especially the edges and corners, especially the angular loofah is less durable and wet, and the roots are easy to rot when soaked in water.

8. Trimming

Loofah has strong branching characteristics. If the stems and leaves are too luxuriant, it is not only easy to grow long and hard to bear fruit, but also to be blown down by the wind during hurricane season. The vine should be cut off early. When cultivating creeping ground, make the main vine grow at right angles to the furrow. In the case of trellis cultivation, if the vines hang under the shed, they should be led to the trellis so that the vines are evenly distributed on the trellis.

9. Cover the border surface

Loofah likes high temperature, has a long growth period and wide row spacing, so it is economical and effective to cover the planting row (on the small crop) with silver-black plastic sheet. If covered with straw, its effect is not as good as silver-black plastic cloth. And when short-fruited varieties are cultivated on creeping ground, the whole border surface should be covered with grass to prevent the fruit from rot in contact with the ground.

10. Fruit bagging and fruit picking

In order to prevent melon fly laying eggs, loofahs are usually bagged, and bagging is done at the young fruit stage after the flowers die. The bagging has the effect of preventing the leaves from scratching the peel and turning the peel into light color. Prevent pesticide pollution. Loofah can be used in old newspaper bags or thicker paper bags.
