I collect gold fingers in the heavens

Chapter 88 Insect Pests
The time came to November 2013.

It has been four months since Wu Siyuan returned from the "Wrangler" movie world.

The site of the new cold storage was also determined and completed, with an area of ​​1300 square meters, and it was named "Dongbao Cold Storage No. 1".

The construction of this new cold storage cost millions of dollars and occupied [Yangcheng Shennong Fruit Industry Co., Ltd.] a large amount of capital flow. Family.

The total number of stores in [Shennong Orchard] is only 20.

At this time, it is summer, the peak season for fruit sales.

In the case of sufficient fruit supply and stable quality as before, relying on the original word-of-mouth advantage and only a little market popularity.

[Shennong Orchard] The sales of each store are rising steadily, and the profits earned are naturally increasing.

For example, in August 2013, after deducting all costs, the company's profit reached as much as 8 yuan, and an average store earned a profit of 85 yuan for the company.

But these profits have been used to invest in fruit planting bases.

In Guangxi Province, [Yangcheng Shennong Fruit Industry Co., Ltd.] took another 3000 mu of wasteland near the original barren hills, and built red meat pitaya orchards, banana orchards, lychee orchards, mango orchards, vineyards and other organic Orchard.

[Yangcheng Shennong Fruit Industry Co., Ltd.] has invested a lot of money here.

However, as Su Shixian said, organic farming is really not a simple matter.

Chemical fertilizers cannot be used for fertilization, only decomposed organic fertilizers can be used. In this way, the cost will be high.

Weeds are overgrown in the orchard, competing with the fruit trees for nutrients. Herbicides cannot be used, and they can only be removed manually. The labor cost will increase, and the cost will be piled up again.

However, these costs are barely acceptable to Wu Siyuan.

After all, if Wu Siyuan's fruit trees are well taken care of, the theoretical yield can be increased by [-]%. In this way, these extra costs can be reduced.

But when encountering insect infestations, they are caught blind.

For example, the recent flat peach orchards in the fruit planting base have encountered a kind of insect pest - aphids!

The main parasitic plants of aphids are peaches, cherries, plums, pears and other fruit trees and mugwort and other compositae plants.

Adults and nymphs gather on the back of the leaves to suck the juice, and the most serious damage is to the young leaves. The edge of the damaged leaves curls longitudinally to the back, and the tissues at the curls are hypertrophic, resembling galls, uneven, light green at first, and then turn red; when serious Most of the leaves are rolled into thin ropes, and finally dry up and fall off, seriously affecting the growth and development of peach trees.

The aphid has the characteristics of small size, fast reproduction and strong concealment.

Using pharmaceutical agents is the fastest way to see results:

During the dormant period of fruit trees, generally before germination, 95 times of 100% engine oil EC can be sprayed to kill overwintering eggs.

未形成伪虫瘿时，可以喷施80%敌敌畏乳油1500倍液或2.5%鱼藤酮乳油500倍液或40%毒死蜱乳油1000倍液或2.5%高效氯氟氰菊酯乳油2 000倍液等药剂进行防治。

After the formation of pseudo galls, the control effect of spraying contact pesticides on the leaves will be relatively poor. At this time, it is best to use 10% imidacloprid wettable powder 2000 times liquid, 1.8% abamectin EC 3 times liquid before leaf curling and other systemic or highly penetrating agents for prevention and treatment.

But the flat peach orchard is to grow organic fruit.

So chemical methods cannot be used!

Only physical control or biological control can be adopted.

This time period is no longer suitable for physical control.

In other words, physical control is used, and the effect is very poor.

Insects are so small and there are so many, how to catch them?

And the effect of biological control is not good.

The aphid is growing unscrupulously in the flat peach orchard just like finding "Lost Paradise".

If pesticides are not sprayed at this time, the output of the orchard will definitely be greatly affected in the future.

But after spraying pesticides, it is no longer an organic fruit, which violates the original intention of [Yangcheng Shennong Fruit Industry Co., Ltd.] to establish this flat peach orchard!

Su Shixian was so worried that his hair fell out.

Finally, the question was fed back to Wu Siyuan.

Wu Siyuan also went to the flat peach orchard in Gui Province to see, under the [detection of spiritual light], it is true that most of the flat peach orchard is shining with the faint but tenacious light of life of mymythosis.

What Su Shixian said is correct, it is very difficult to solve the rampant aphid without spraying pesticides.

But after spraying pesticides, the flat peach orchard has no meaning of existence.

Wu Siyuan was also caught in a dilemma.

He held many company management meetings and brainstormed ideas, but he was at a loss and had no clue.

Once, Lin Meiyi said bitterly, how wonderful it would be if there were beneficial insects or plants that eat a lot of pests!

The speaker is unintentional, but the listener is intentional.

Forget about beneficial insects, ladybugs, lacewings, hoverflies, and wasps are far away from the fire and cannot save the near fire.

But when it comes to plants...

Nature has magical powers and has bred many strange creatures.

Under normal circumstances, plants are in the victim stage, that is, during the growth process, they will be "bullyed" by many "bully" pests!
A few plants may have more personality and have some means of resistance, but these means are mainly expelling.

However, there are some plants whose identities are reversed, from [victim] to [perpetrator], from passive attraction to active seduction.

Among them, the most famous and well-known ones are the rope-catching plants and the pitcher plants.

Flytrap is a perennial herb native to North America. It is a very interesting carnivorous plant. Its stem is very short, and there is a "shell" insect trap on the top of the leaf, which can It secretes honey juice, and when a small insect breaks in, it can clamp it at a very fast speed and digest and absorb it.

Because there are regular bristles on the edge of the leaves, it feels like the eyelashes of Venus, which means [Venus's Fly Trap], and it also has the alias of [Fly Hell].

Flytraps are known as nature's carnivorous plants.

Nepenthes is a tropical carnivorous plant, and its origin is mainly in the tropical regions of the Old World. It has a unique organ for absorbing nutrients - [pitcher].

The pitcher is cylindrical, with a slightly enlarged lower part and a lid on the mouth of the pitcher. It is named for its shape like a pig cage.

The structure of Nepenthes leaves is complex, divided into petioles, leaf bodies and tendrils.The tendril tail expands and curls back to form a bottle, which can prey on insects.

The cover surface of the bottle-shaped body can secret fragrance and attract insects.The mouth of the bottle is smooth, and the insects will slide down into the bottle, drowned by the liquid secreted from the bottom of the bottle, and decompose the nutrients of the insect body, and gradually digest and absorb them.

Wu Siyuan purchased a batch of these carnivorous plants on his own and began to do research.
