I'm collecting golden fingers from all over the world

The time came to September 2013.

Four months have passed since Wu Siyuan returned from the "Wrangler" movie world.

The location of the new cold storage was also determined and construction was completed. It covers an area of ​​1,300 square meters and was named "Winterburg Cold Storage No. 1".

The construction of this new cold storage cost millions of dollars and occupied a large amount of capital flow from [Yangcheng Shennong Fruit Co., Ltd.], which indirectly led to the fact that [Shennong Orchard] did not open many new stores during this period, only 7 Home.

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

It is summer, the peak season for fruit sales.

With sufficient supply of fruit and stable quality as always, we rely on our original reputation advantage and little market visibility.

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

For example, in August 2013, after deducting all costs, the company's profit reached 850,000 yuan. On average, one store earned the company 42,500 yuan in profit.

But all these profits were used to invest in fruit planting bases.

In Guangxi Province, [Yangcheng Shennong Fruit Co., Ltd.] acquired another 3,000 acres of wasteland near the original barren mountains and built a red-fleshed dragon fruit orchard, banana orchard, lychee orchard, mango orchard, vineyard and other organic Orchard.

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

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

You cannot use chemical fertilizers for fertilization, you can only use decomposed organic fertilizers, which will increase the cost.

The orchards are overgrown with weeds, which compete with the fruit trees for nutrients. Herbicides cannot be used and can only be removed manually. The labor costs have increased and the costs have been piled up again.

However, Wu Siyuan can barely accept these costs.

After all, if Wu Siyuan's fruit trees are taken care of well, the theoretical output can be increased by 30%. In this case, these additional costs can be spread down.

But when it comes to insect infestation, it is blind.

For example, the peach orchard in the fruit planting base recently encountered a pest - myrtleoxera!

The main parasitic plants of the myrtle aphid include fruit trees such as peaches, cherries, plums, and pears, and Asteraceae plants such as mugwort.

Adults and nymphs swarm on the back of leaves to suck sap, and young leaves are most severely affected. The edges of the affected leaves are curled longitudinally toward the back. The tissue at the curls is thick, gall-like, and uneven. It appears light green at first and then turns red; in severe cases, it looks like galls. Most of the leaves are rolled into thin ropes and eventually dry up and fall off, seriously affecting the growth and development of the peach tree.

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

Using pharmaceutical agents is the fastest way to achieve results:

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

When pseudogalls are not formed, you can spray 80% dichlorvos EC 1500 times, 2.5% rotenone EC 500 times, 40% chlorpyrifos EC 1000 times, or 2.5% beta-cyhalothrin EC 2000 times. Prevention and treatment.

After pseudogalls are formed, the control effect of contact pesticides sprayed on the leaves will be relatively poor. At this time, it is best to use 10% imidacloprid wettable powder 2000 times liquid and 1.8% abamectin emulsifiable concentrate 3 000 times liquid before leaf rolling. Use systemic or highly penetrating agents for prevention and treatment.

But Pantao Orchard grows organic fruits.

Therefore, chemical methods cannot be used!

Only physical control or biological control can be adopted.

This period is no longer suitable for physical control.

In other words, physical control was used, but the effect was very poor.

The bugs are so small and there are so many bugs, how do you catch them?

The effect of biological control is not good either.

The myrtle aphid is like finding a "lost paradise", growing unscrupulously in the peach orchards.

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

However, if pesticides are sprayed, the fruit is no longer organic, which violates the original intention of [Yangcheng Shennong Fruit Co., Ltd.] to establish this flat peach orchard!

Su Shixian was so worried that his hair was falling out.

Finally, the question was fed back to Wu Siyuan.

Wu Siyuan also went to the peach orchards in Guizhou Province to see. Under the [Detection Light], it was true that most of the peach orchards were shining with the weak but tenacious light of life of the myrtle aphid.

Su Shixian is right. Without spraying pesticides, it is difficult to deal with the spread of the myrtleoxera.

But after the pesticides were sprayed, the peach orchards lost their meaning of existence.

Wu Siyuan was also in trouble.

He held many company management meetings to brainstorm ideas, but he was unable to do anything and had no clue.

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

The speaker does not mean it, but the listener does it intentionally.

Forget about beneficial insects, ladybugs, lacewings, hoverflies, and aphid wasps are things that cannot be saved by distant water.

But as for plants...

Nature has magical power and has given birth to many strange creatures.

Under normal circumstances, plants are in the victim stage, that is, during the growth process, they will be "bullied" by many "bully" pests!

A few plants may have more personality and some means of resistance, but these means are mainly for repelling them.

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

Among them, the most famous and well-understood is the rope plant and pitcher plant.

The Venus flytrap is a perennial herb native to North America. It is a very interesting carnivorous plant. It has a very short stem and a "shell"-like insect trap on the top of the leaf. It can It secretes honey, and when a small insect breaks in, it can be caught at an extremely fast speed and digested and absorbed.

Because there are regular bristles on the edges of the leaves, they feel like Venus's eyelashes, which means "Venus' fly trap". In addition, it also has the nickname "Hell of Flies".

The Venus flytrap is known as a carnivorous plant in nature.

Nepenthes is a tropical carnivorous plant. Its origin is mainly in the tropical areas of the Old World. It has a unique organ for absorbing nutrients - [Pitcher].

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

The structure of pitcher plant leaves is complex, divided into petioles, leaf bodies and tendrils. The tail of the tendril expands and curls up to form a bottle shape, which can capture insects.

The cover of the bottle-shaped body can secrete fragrance and attract insects. The mouth of the bottle is smooth, and the insects will slip into the bottle and be drowned by the liquid secreted from the bottom of the bottle, which will 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 study them.
