The soil where crops are planted for many years is prone to diseases and insect pests, which adversely affect the growth, flowering and fruiting of crops. Fruit and vegetable planting, early occurrence of dead seedlings can be pulled out and replanted, the impact of dead seedlings after flowering and fruiting on the yield of strawberries can be said to be fatal. So, what is the reason for the strawberry seedlings? What if it is always dead seedlings? Let's take a look.
<h1 class="pgc-h-arrow-right" data-track="56" > What is the cause of strawberry seedlings</h1>
1. Excessive pursuit of yield in the process of vegetable and fruit planting, excessive fertilization leads to soil salinization or serious compaction, strawberry capillary root growth or rapid death, root system water absorption difficulties, poor growth and development or dead trees.
2. Heavy stubble planting leads to an increase in harmful bacteria in the soil, and the presence of strawberry blight, root rot or root knot nematodes leads to serious occurrence of dead strawberry seedlings.
3. Ignoring soil-borne diseases leads to a significant increase in the incidence of blight, vine blight and green blight in the late growth of strawberries, resulting in the situation of plant wilting and dead trees in the middle and late stages.
4. The soil has been planted for many years, the nutrient consumption is too much, and the land ploughing and insufficient water and fertilizer application before planting lead to insufficient nutrition at the strawberry seedling stage, resulting in poor growth and development of the seedlings.
5. After fertilizing the soil that has not been completely decomposed, the fertilizer is fermented in the soil and the heat is too much, resulting in the burning of seedlings as dead seedlings.
Strawberries are always dead seedlings, and after excluding the reasons for the variety and root system of the seedlings (first breeding and then colonization), it is necessary to consider the impact of soil factors and growth climate on the growth and development of strawberries.
<h1 class="pgc-h-arrow-right" data-track="68" > What should I do if strawberries are always dead seedlings? Plant what fertilizer under the strawberries</h1>
In view of the situation of dead seedlings and rotten trees caused by soil causes, it is necessary to make corresponding preparations and prevention work when planting strawberries under fertilizer.
Planting strawberry fertilizer, the base fertilizer is mainly decomposed farm manure, high-quality organic fertilizer, in the soil structure is not very good land, must be synchronously sprinkled with microbial bacterial fertilizer for soil regulation and related disease prevention and control.
Strawberry field fertilization uses special water-soluble fertilizer for root substitution and root rot, rich in effective live bacteria greater than or equal to 200 million / ml, and adds a variety of gene enzymes, energy diffusers and other substances to promote the complementary advantages of nutrient coexistence, regulate soil structure, promote the development of crop roots, enhance the disease resistance and stress resistance of strawberries, make crops grow robustly, improve quality, increase yield and income.
Strawberry in the middle and late stage of cultivation of strong seedlings, strong seedlings to promote growth, can avoid the flowering stage to avoid the use of Kunlun wind, Yun Xi harvest and other foliar fertilizer packages at intervals of about 10 days continuous spraying 2-3 times, can be a good reduction in the incidence of common diseases in the strawberry growth period, the seedlings are robust, the disease resistance is enhanced, and the occurrence and impact of common diseases are effectively coped with.
