Relying on "Guerilla Fighting" to Prevent Diseases

"This watermelon is crispy and can be broken with a stroke of your hand
.
" When the reporter was interviewing in Xuxu Township, Huaiyuan County, Bengbu City, Anhui Province recently, the guardian of the melon farmer picked up a watermelon and showed it to the reporter
.
Laozong’s watermelon variety is "8424", which is characterized by its sweetness and crispness
.
In order to show reporters how crisp this watermelon is, Lao Zong used his fingernails to lightly scratch the bottom of the watermelon, and then broke it hard, and the watermelon cracked
.
"This kind of watermelon is too crisp to be transported, so it is mainly supplied to the local market
.
" Lao Zong told reporters
.
Although the main supply is local, the efficiency is not low
.
There is another variety "Carnival No.
5" in Lao Zong's watermelon field, which is mainly sold in Hunan, but the purchase price per catty is lower than "8424" by 30 cents
.
"Since 2010, I have been planting the '8424' variety on Chongming Island in Shanghai.
At that time, it was close to Shanghai, a big market, and it sold very well
.
When I returned to Xuxu Township in 2013, I continued to plant it naturally
.
" Tell the reporter his planting story
.
"In fact, the variety '8424' is more suitable for our Xuxu climate.
It is prone to low temperature damage in winter to the north, and rainwater in summer to the south
.
" added Shang Yue, chairman of the Shengshixingnong Watermelon Professional Cooperative in Huaiyuan County
.
Shang Yue is a well-known big grower in Xuwei Township.
This year his cooperative has planted a total of 480 mu of watermelon, and Lao Zong rented his 20 mu of land for management
.
"I rented the land from Mr.
Shang at a price of 1,500 yuan per mu, and then removed the cost of film, greenhouse, fertilizer, etc.
, and I could make a net profit of 80, 90,000 yuan a year
.
" Lao Zong said
.
Today, the Lao Zong couple can live a prosperous life on these 20 acres of land
.
Having said that, Old Zong went to the shed again to tidy up the branches and leaves of the watermelon
.
"It is necessary to arrange the branches and leaves regularly to let the nutrients moisturize the watermelon as much as possible
.
" Lao Zong has a set of experience in planting watermelons.

.
Now, Lao Zong's watermelon fields have also begun to use drip irrigation
.
"There are pipes buried in the ground, which can easily realize the integration of water and fertilizer
.
" When it comes to growing watermelons, the old man is very proud
.
In order to better take care of the watermelon, Lao Zong set up his home next to the greenhouse
.
But when the reporter and Lao Zong walked into the house together, they found that the furnishings in the house were very simple
.
"My watermelon field needs to be moved once a year, so the house is naturally easier
.
" Lao Zong told reporters
.
It turned out that because of the adherence to the pollution-free planting method, in order to prevent watermelon from being infected with fusarium wilt, only one season of watermelon can be grown on the same land within five years, and the old man had to "fight guerrilla" all year round
.
"Our watermelons here change a place every year.
When I signed the agreement with Lao Zong, I agreed in advance to ensure that he can find suitable land every year
.
" Shang Yue added
.
The method of "playing guerrillas" also made Lao Zong put in a lot of labor
.
Ditches are built between each greenhouse in the plantation.
The trenches on both sides of the main road are deeper, and the deepest place is nearly 1.
5 meters.
The construction cost of each greenhouse is 5,000 to 6,000 yuan
.
"When you change a place every year, these infrastructures have to be rebuilt.
It takes two months to build the plantation alone.
With the addition of eight or nine months of watermelon growth, there is almost no idle time a year
.
" Said the boss
.
These two days have been the busiest time for Lao Zong.
This year's first watermelon will soon be on the market.
Saying goodbye to the reporter, Lao Zong returned to the watermelon field to get busy
.
Although old varieties like the "8424" watermelon need to rely on the "guerrilla" method to solve their own limitations, the economic benefits of the new varieties show that the market competitiveness of some old varieties should not be underestimated
.
These problems in the cultivation of melon farmers and the diversified needs of the market place higher demands on breeders.
We look forward to the emergence of more excellent new varieties, and we also hope to see the improved old varieties create brilliance again.

.
Eliminating the dross and choosing the essence is not only used in planting technology, but also in the breeding of varieties.
The old varieties that have been updated and upgraded can also meet the needs of the market
.
